Document `base` more clearly
Our current docs for base says that we will start your server at the specified path (so localhost:3000/base rather than localhost:3000). But what else does it do? It can seem like it's supposed to affect your import paths (see this support thread message), like the <base> tag, but it doesn't.
That is right. Should we open a new PR now?
I am doing this at #1671.
This documents the current behavior, but we now know that this current behavior is unintended. Waiting on this issue to be fixed, and then we'll need to document the corrected behavior
Followup: No longer blocked, and https://github.com/withastro/astro/pull/5693 has been made to address this. Comments can be made there!
Thanks for your contributions, everyone!
