chore: handle quotes properly in metadata updater (#34990)

### Issue # (if applicable)

Related to #34863.

### Reason for this change

Because the linked PR contains quotes inside the enum values, the metadata updater produces invalid typescript code: see fe7e986

### Description of changes
This change fixes the handling of the cases:
Single quotes inside an enum value: `'\''`, instead of being translated to `'''` (which is not valid typescript), will be escaped properly.

Double quotes inside an enum value: `'"'` will get translated to `'\''` (which is valid typescript but not what we expect), will be escaped properly.



### Description of how you validated changes


Ran the Github workflow in my account, and then built the created PR and ran unit+integ tests
