fix edge case with periods in keys

[daniel-trinh]

What does this PR do?

Fixes the Ruby code formatter to correctly handle hash keys containing special characters (e.g., periods, dashes, spaces) by using hash rocket syntax (=>) instead of symbol syntax.

Problem:
The formatter was generating invalid Ruby syntax for keys with special characters like "ocsf.activity_name":

# Before (invalid syntax):
{ ocsf.activity_name: 'Other' }

Solution:
Added validation to check if a key is a valid Ruby symbol. Keys with special characters now use hash rocket syntax:

# After (valid syntax):
{ "ocsf.activity_name" => 'Other' }

Valid identifiers (alphanumeric and underscores only) continue to use symbol syntax:

{ normal_key: 'value' }

Additional Notes

• Added Ruby tests to verify correct behavior for both valid and invalid identifiers
• No schema changes required

Review checklist

• This PR includes all newly recorded cassettes for any modified tests.
• This PR does not rely on API client schema changes.
  • The CI should be fully passing.
