feat(ci): Allow commas in PR titles

[umfranzw]

Motivation

Currently, the libraries pr-bot does not allow commas in PR titles.
In primitives libraries PRs, we have libraries that are dependent on each other,
so sometimes it's useful (or just convenient) to modify multiple libraries in the
same PR (eg. #8439).
Prior to the introduction of the pr-bot, in cases like this, in the PR title, we had been
separating the library names with commas.
Eg. "fix(hipcub,rocprim) title text..."

Technical Details

This change modifies the pr bot's regex to allow commas between the parenthesis.

Test Plan

Run the updated bot on a PR that has commas between the parenthesis in the title.

Test Result

TBD - will test as soon as I'm able.
