fix(outlook): Tweak outlook format to be plain text instead of html (#45

)

## Describe your changes
Output text instead of html

## Issue ticket number and link

## 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
