[PATCH 2/2] docs: python: abi_regex: convert adjacent index placeholders

While validating recent CXL ABI documentation updates with
get_abi.py, every decoderX.Y entry was reported as undocumented.

The placeholder conversion mishandles adjacent index placeholders,
producing patterns that cannot match the corresponding sysfs paths.
As a result, valid ABI entries are reported as undocumented.

Handle adjacent placeholders independently so generated patterns match
the documented paths. This fixes decoderX.Y entries in the CXL ABI and
other ABI documentation that uses the same naming convention.
