Bumps [google.golang.org/grpc](https://github.com/grpc/grpc-go) from1.76.0 to 1.77.0.<details><summary>Release notes</summary><p><em>Sourced from <ahref="https://github.com/grpc/grpc-go/releases">google.golang.org/grpc'sreleases</a>.</em></p><blockquote><h2>Release 1.77.0</h2><h1>API Changes</h1><ul><li>mem: Replace the <code>Reader</code> interface with a struct forbetter performance and maintainability. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8669">#8669</a>)</li></ul><h1>Behavior Changes</h1><ul><li>balancer/pickfirst: Remove support for the old<code>pick_first</code> LB policy via the environment variable<code>GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST=false</code>. The new<code>pick_first</code> has been the default since <code>v1.71.0</code>.(<ahref="https://redirect.github.com/grpc/grpc-go/issues/8672">#8672</a>)</li></ul><h1>Bug Fixes</h1><ul><li>xdsclient: Fix a race condition in the ADS stream implementationthat could result in <code>resource-not-found</code> errors, causing thegRPC client channel to move to <code>TransientFailure</code>. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8605">#8605</a>)</li><li>client: Ignore HTTP status header for gRPC streams. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8548">#8548</a>)</li><li>client: Set a read deadline when closing a transport to prevent itfrom blocking indefinitely on a broken connection. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8534">#8534</a>)<ul><li>Special Thanks: <ahref="https://github.com/jgold2-stripe"><code>@​jgold2-stripe</code></a></li></ul></li><li>client: Fix a bug where default port 443 was not automatically addedto addresses without a specified port when sent to a proxy.<ul><li>Setting environment variable<code>GRPC_EXPERIMENTAL_ENABLE_DEFAULT_PORT_FOR_PROXY_TARGET=false</code>disables this change; please file a bug if any problems are encounteredas we will remove this option soon. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8613">#8613</a>)</li></ul></li><li>balancer/pickfirst: Fix a bug where duplicate addresses were notbeing ignored as intended. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8611">#8611</a>)</li><li>server: Fix a bug that caused overcounting of channelz metrics forsuccessful and failed streams. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8573">#8573</a>)<ul><li>Special Thanks: <ahref="https://github.com/hugehoo"><code>@​hugehoo</code></a></li></ul></li><li>balancer/pickfirst: When configured, shuffle addresses in resolverupdates that lack endpoints. Since gRPC automatically adds endpoints toresolver updates, this bug only affects custom LB policies that delegateto <code>pick_first</code> but don't set endpoints. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8610">#8610</a>)</li><li>mem: Clear large buffers before re-using. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8670">#8670</a>)</li></ul><h1>Performance Improvements</h1><ul><li>transport: Reduce heap allocations to reduce time spent in garbagecollection.

(<ahref="https://redirect.github.com/grpc/grpc-go/issues/8657">#8657</a>,<ahref="https://redirect.github.com/grpc/grpc-go/issues/8667">#8667</a>)</li><li>mem: Avoid clearing newly allocated buffers. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8670">#8670</a>)</li></ul><h1>New Features</h1><ul><li>outlierdetection: Add metrics specified in <ahref="https://github.com/grpc/proposal/blob/master/A91-outlier-detection-metrics.md">gRFCA91</a>.
