-builtins calver release is a go

First job failed due to a stupid error but was published by hand, second one may fail for other reasons, we'll see.

Reposting the reasoning of #277:

• uap-core has not cut a release in more than 2 years (31 months) https://github.com/ua-parser/uap-core/releases/tag/v0.18.0 being the latest official release as of writing this
• users have been requesting updates to the way-outdated precompiled regexes (YaSearchBrowser UA is mis-detected as Chrome — bundled uap-core is outdated #270, Bump uap-python-builtins as it's 8 months out of date #271)
• request for official guidance has yielded no feedback in 3 months (Plans for releases / tagging of regexes.yaml? uap-core#641)
