[PATCH v2 1/2] docs: python: abi_regex: catch the right exception for a bad regex

While validating recent CXL ABI documentation updates with
get_abi.py, the 'undefined' mode was found to abort instead of
reporting undocumented ABI entries.

Older Python releases raise re.error, while newer releases expose
re.PatternError. Catching the compatible re.error exception handles
both cases.

Use re.error so the scan continues and reports the remaining
results.

Changes in v2:
- Update commit msg to say catches the compatible re.error (Sashiko)
- No code change
