Fixes: #52787
What?
Updated the regex in the valid-sprintf ESLint rule to correctly handle escaped percent signs (%%). Added 4 new test cases that cover various scenarios involving %%.
Why?
The current regex fails to handle cases like sprintf('Rotated at %d %% degrees', 90) by mistakenly flagging valid format strings with escaped percent signs as incorrect. This update ensures proper handling of %d %% and similar cases.
