chore: updated ignore pattern

[blunteshwar]

Our metadata.json files in component dist folders were being ignored even though we didn't want them to be. This was happening because the simple dist ignore rule was too broad and was overpowering our exception rule. Due to this husky/pre-commit was throwing error.
Updated the .gitignore to use more precise patterns:
**/dist/* # First ignore everything in any dist folder
!**/dist/metadata.json # Then make exception for metadata.json

*/dist/ - ignores contents of dist folders at any depth
The exception rule now properly matches the ignore pattern

How and where has this been tested?
