Repetition rule gets thrown off at the end of a sentence?

[alexpdp7]

Describe the bug

Apparently, https://github.com/redhat-documentation/vale-at-red-hat/blob/main/.vale/styles/RedHat/RepeatedWords.yml gets thrown off at the end of a sentence.

Examples:

• This is a test test. <--- doesn't get flagged, because of the trailing period.

To Reproduce

Steps to reproduce the behavior:

1. Just test the sentence above.
2. Doesn't get flagged.

Expected behavior Should be flagged.

Additional context I haven't tested this with your full configuration- we use a different .vale.ini, so perhaps this doesn't happen with your full config (I fiddled a little bit copying token ignores, etc. from your .vale.ini and it was still a problem.

I confirmed that this issue is valid. The rule does not catch a repeated word at the end of a sentence like "This is a test test."

Some notes to share my process with others who might be interested in doing similar work:

• I added "This is a test test." to .vale/fixtures/RedHat/RepeatedWords/testinvalid.adoc and pushed the changes in a PR. As reported above, the PR failed to detect this repetition and threw an error.
• I googled "regex to catch repeated word" and found a better regex for catching duplicate words here: https://stackoverflow.com/a/12309899
• I validated this regex against the test phrase in https://regex101.com/
• I updated the value of token in .vale/styles/RedHat/RepeatedWords.yml with the new regex.
• I pushed these changes to https://github.com/redhat-documentation/vale-at-red-hat/pull/322 to see if the checks pass.
