This is a pull request to fix Twig 3.15 inline comments. (#8100)

Before :

After:

It is not a perfect solution as the following snippet will be seen as normal.

{{ "Hello World"|upper # this is an inline comment }}

This snippet will trigger a parser error on a real usage.
Unfortunately, the fix for this is more complex and can take more time as it is done on twig top lexer.
I need to check if the "#" symbol is in string or not, if it will finish with a new line or not, for which I sense that jflex lexer has some limitations and the current logic is hard to adapt.
