PKCE Support for OAuth 2.0

We've added support for OAuth Authorization Code flow with Proof Key for Code Exchange (PKCE).

When creating a new OAuth 2.0 credential with Authorization Code grant type, you'll have the option to select a PKCE code challenge method.

This PKCE code challenge method is optional when creating OAuth credentials. You may select either plain or SHA-256 if you know the OAuth provider you're creating a credential for supports PKCE.

For more information on PKCE, see the RFC.

New folder icons and more color options

We've added more folder icons to choose from, as well as added the capacity to pick your own colors for them using hex color values.
