[Bug] Broken Links in ATT&CK-coverage.md

[shashank-elastic]

Describe the Bug

The AWS wildcard Link in ATT&CK-coverage.md is broken, It is because all of the rules using it either updated the index to be more specific or are deprecated and the update logic does not remove any links for such a scenario in ATT&CK-coverage.md.

To Reproduce

1. Go to https://github.com/elastic/detection-rules/blob/main/docs/ATT&CK-coverage.md
2. Click on Link Elastic-detection-rules-indexes-logs-awsWILDCARD
3. See the error

Expected Behavior

If there are no rules pointing to the index and the GIST is not updated, the Link in ATT&CK-coverage.md should be removed.

Lets look at the solution of always updating the ATT&CK-coverage.md file with the latest information.
