Remove scheme from URI before fetching path for CRL path check (#2622)

* Remove scheme from URI before fetching path for CRL path check

* Update src/main/java/com/microsoft/sqlserver/jdbc/ConfigurableRetryLogic.java

Co-authored-by: Copilot <[email protected]>

* Committed nitpick mentioned by copilot

* Added additional check + greater clarity

* The issue was with jar:file:/ NOT jar:/, corrected.

* Forgot a case where there would be no scheme
