zeta: Add zlib to license detection + ignore symbol differences (#37238)
Michael Sloan created
See discussion on #36564. Makes the license regexes a less fragile by
not matching on symbols, while also excluding cases where a long file
ends with a valid license. Also adds Zlib license, a commented out test
to check all license-like files discovered in the homedir, and more
testcases.
Not too happy with the efficiency here, on my quite good computer it
takes ~120ms to compile the regex and allocates ~8mb for it. This is
just not a great use of regexes, I think something using eager substring
matching would be much more efficient - hoping to followup with that.
Release Notes:
- Edit Prediction: Added Zlib license to open-source licenses eligible
for data collection.Change summary
