feat: added support multiple parameters in .startsWith() and .endsWith() in string for ticket #3683

[Kumar06Lav]

Added support for multiple parameters in the .startsWith() and .endsWith() methods for string validation. This enhancement allows for more versatile input checks by enabling validation against an array of possible starting or ending values.

This implementation was done for ticket #3683

Changes:

Modified the .startsWith() method to accept an array of valid prefixes. Implemented the .endsWith() method to validate strings against multiple suffixes. Added test cases to verify the new functionality. Updated documentation to reflect the changes and provide usage examples.
