Create a docs page that explains all toast error messages

Problem

Currently, when users encounter an error message, they're often sent to the community question page, which isn't very useful.

As per this insight flagged by @joethreepwood, these users often end up raising a support ticket.

Suggested solution(s)

• Create a docs page that explains all the toast errors, what they mean, and what the user should do about them.
• Have toast messages point to this new page, instead of sending people to questions.
• Potentially identify bad error messages and improve them.

@MarconLP @abigailbramble @slshults @darkopia @benHPostHog -- If there are errors you've got questions about, heard questions about, or seen then would be good to add them here please!

• We can probably find the toast component in app and find all the places it is used.
• Better than creating toast pages, would be creating and linking to FAQ for the specific products
