fix(ui): Sentry Apps: Vertical CircularIndicator and capitalize (#36576)

For instance, when loading the Linear app, the circular indicator would not line up with the text.

You can see this working by running `yarn dev-ui` (sign in with a non-SSO org) and load this page:
https://localhost:7999/settings/sentry-ecosystem/sentry-apps/linear/

This also capitalizes the name of the app when the installing/uninstalling apps.

Fixes Jira ticket: API-1173
