Description
Describe the bug
Using a pattern like "pattern": "(?i)(SecurityGroup)", wil break all validation in the same scheme,
Expected Behavior
Should work, same scheme works just fine for json documents with the build-in extension in vscode. Also validates fine with regex engines i tried.
Current Behavior
With error: Message: Request textDocument/hover failed with message: Invalid regular expression: /(?i)(Dynamic|Static)/: Invalid group
Steps to Reproduce
Use any pattern beginning with (?i) in your scheme.

Research direction
Reproduce the failure with a schema pattern beginning with (?i) and compare it with the working JSON-schema behavior described in the issue. Trace the YAML language server's pattern validation and hover path, then verify that case-insensitive patterns no longer produce an invalid-regular-expression error without breaking validation for the rest of the schema.
