Bug 1811450 - Do not cap Firefox version on profiler metadata r=florian

Since Bug 1805967 Firefox version is capped to 109 due to some web
compatibility issues. This resulted us to add the wrong Firefox version in the
profiler metadata. We don't have the same webcompat related concerns and it's
important to see the real version so data is more accurate when performance
engineers look at the profiles of others.

This http misc field was populated here:

and UA version comes from this function which uses `MOZILLA_UAVERSION` directly:
