Update install.md

Added a note regarding access to the live folder by nginx user. (this lack of access bit me :-)

[vercel]

@glowrocks is attempting to deploy a commit to the Mastodon Team on Vercel.

A member of the Team first needs to authorize it.

That shouldn't be needed… nginx should not need write access to anything, and it should not need read access to /home/mastodon, only traversal access. So 711 should be enough.

Correct. I've confirmed that is correct. What's the next step? (I've never done this before.)

Wanted to add, on Ubuntu 22.04, adduser leaves the home dir w/no access for other. So while 755 is too permissive, the default of 750 is what causes the problem.
