Fix Pull Request comment filename word breaks (#19535)

* Fix word breaks in Chrome

This fixes word wrapping on the filename for a comment on a PR. A previous commit fixed this problem in Firefox, but not Chrome.

Fixes #16248

* Don't break Outdated badge

This prevents the Outdated badge on a PR from wrapping in the middle of the word for a comment on a long filename.

* Move word break to recommended element

* Add overflow-wrap per PR review

* Update web_src/less/helpers.less
