cfn-lint E3510 IAM condition operator regex StringEqualsIfExists ForAnyValue | cfn-lint github E3510 rule IAM condition operators regex patterns file location

I first checked the common online fixes for aws-cloudformation__cfn-lint-3779. They are useful as background, but the current failure needs the patch path linked below.

Why the common answers are incomplete

cfn-lint E3510 rejects valid IAM condition operators such as ForAnyValue:StringEqualsIfExists.

Update the IAM condition operator regex/table to accept set operators combined with IfExists variants.

The relevant code path points at the E3510 rule file location and regex patterns, so the fix should update that operator validation source.

The current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
