Add Figma Personal Access Token v3 Detector (#4790)

* added v3 for figma pat

* fix regex pattern and tests in v3

* add verification function in a separate file

* add secretparts to results in figma detector

* Gate Figma v3 detector behind feature flag

* fix failing tests

* address review feedback on figma detector

* Add unit tests for Figma VerifyMatch

* restore comments

* verify Figma tokens by parsing the 403 response body
