about:debugging page indicates that the About Sync extension has an invalid version number

STR:

1. Install the About Sync add-on from https://addons.mozilla.org/en-US/firefox/addon/about-sync/
2. Visit about:debugging and scroll down to the entry for About Sync (under "Extensions")

ACTUAL RESULTS:
There's a warning box -- if you expand it, it shows the following:

Warning details

Reading manifest: Warning processing version: version must be a version string consisting of at most 4 integers of at most 9 digits without leading zeros, and separated with dots

Here's a screenshot:

EXPECTED RESULTS:
No such warning (i.e. we probably need a conforming version numbering scheme).

If you look at the Version field on https://addons.mozilla.org/en-US/firefox/addon/about-sync/ , you can see that indeed our version number does not conform to this "at most 4 integers of at most 9 digits without leading zeros, and separated with dots" scheme -- we have right now:

Version
    0.21.0buildid20220714.054802

I'm using Firefox Nightly, version 111.0a1 (2023-01-21) (64-bit)

This isn't unexpected but it isn't a problem as long as this extension continues to be a MV2 extension. This new version string format is enforced for MV3+ extensions. This will need to be fixed in the pipeline itself, see mozilla-extensions/xpi-manifest#185
