Adding Claude Vale rules review script

[aireilly]

Script to automate Vale rule term reviews to filter out false postives or terms that are not useful to have in the rules. The script does not add new terms.

The script was created using Claude Code and does the following:

1. Clones a docs repo and runs Vale with RedHat rules against the repo adoc
2. Dedupes errors to identify unique false positives across files
3. Uses Claude Code CLI to review errors and determine which are false positives
4. Updates Vale rules and test fixtures to exclude false positives (modifying .yml files and
   .adoc test files)

Example output:
#981
#980
