chore: Fix up google drive sync description

[nalanj]

to make mintlify happy

Describe your changes

For the docs updates in the other repo, Mintlify really doesn't like this drive description having curly braces in it, so I'm making it code to fix the issue up.

Checklist before requesting a review (skip if just adding/editing APIs & templates)

• I added tests, otherwise the reason is:
• External API requests have retries
• Pagination is used where appropriate
• The built in nango.paginate call is used instead of a while (true) loop
• Third party requests are NOT parallelized (this can cause issues with rate limits)
• If a sync requires metadata the nango.yaml has auto_start: false
• If the sync is a full sync then track_deletes: true is set
• I followed the best practices and guidelines from the Writing Integration Scripts doc
