PR Summary

PR adds libicu76 as a valid dependency for the.deb andfixes#25865.

PR Context

• Debian 13 only has libicu76 in the trixie repository, thus it is not possible to use the.deb to installpwsh on Debian 13. However you can usethe binary just fine.
• This change is required in addition tothe .NET 10 change as Solver3 only has access tolibicu76 in the trixie repo.
• I have tested this by building pwsh and the.deb locally using .NET 10 prior to making the change and got the error specified inUnable to install 7.5.4 on Debian 13 (Trixie) due to unmet dependency on libicu[74|72|70|69|68|67|66|65|63|60|57|55|52] #25865; then once the change was made, rebuilt the.deb and got a working install.
