Add label for Firefox/100

There will be a running experiment (driven by the experiment team, piloted by @cpeterso ) very soon for people using Nightly in Firefox we should

• [x] add label for version100 in the labels list
• [ ] create tests for Firefox/100 and Chrome/100 UA string
• [ ] detect that the reported user agent version is Browser/100 and automatically assign the label

That will help the webcompat team to identify a "potential source" for the issue.

@cpeterso when do we start the experiment? So we can deploy it on webcompat.com side before it's on.

Happy to help review this change.

I don't have an exact date yet. I'm hoping before the end of August, but it won't happen sooner than August 20.

perfect it gives me time to polish the backend and have the approval of @ksy36

Well I have found a website that with 100 in the user agent doesn't work but there is this flag now? It is https://core.trac.wordpress.org/ that have spambot detection in case user agent is not valid. I already reported to them.

Thanks @Mte90 - the best place to report site bugs is webcompat.com/issues/new - this repo tracks site development.

(And also, huge thanks for reaching out).

maybe can be closed now?

Yeah, let's close this as the experiment is over and we're in 104 now.
