feat(app-store): add feishu calendar

[techknowlogick]

What does this PR do?

Cal.com supports Lark, the international version of Feishu. However, depending on where your tenant is, you cannot use the Lark connection.

This PR adds an app for users who are in the Feishu tenant.

Fixes #12953

Type of change

• Bug fix (non-breaking change which fixes an issue)
• Chore (refactoring code, technical debt, workflow improvements)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Tests (Unit/Integration/E2E or any other test)
• This change requires a documentation update

How should this be tested?

• Create an org on feishu.cn with an example user that has a calendar
• Create a new app at https://open.feishu.cn/ and get the app ID and secret to be used, and connect that in your dev environment
• Install app and test that it pulls in the calendar
• Confirm that events can't be booked at the same time as something already scheduled in the linked feishu calendar

(I can provide test keys/whatnot via PM if you don't wish to create an account yourself)

Mandatory Tasks

• Make sure you have self-reviewed the code. A decent size PR without self-review might be rejected.
