Audit how to request support in docs

[et]

We have lots of different pages of how to find support. We should be consistent in the docs.

• Example - hit us up in [our community](https://highlight.io/community) or send us an email.
• Example - If you'd like us to support a new framework, feel free to shoot us a message at [[email protected]](mailto:[email protected]) or drop us a note in our [discord](https://discord.gg/yxaXEAqgwN).
• Example - Send us an email ([[email protected]](mailto:[email protected])) or intercom ticket with your domain

Ideally, we should be using some type of shared logic so we can keep this consistent.

Alternatively, we can just remove any inline support suggestions and the user can just rely on support links via the navigation menu.
