Possibly stale docs for building without docker-compose

[nolash]

Trying recipe in https://forge.rust-lang.org/docs-rs/no-docker-compose.html but halted by these database subcommands that don't exist any longer on the version I have:

$ cargo run database update-search-index
[...]
error: The subcommand 'update-search-index' wasn't recognized
[...]
$ cargo run database update-release-activity
[...]
error: The subcommand 'update-release-activity' wasn't recognized
[...]

my docs.rs commit: 3d582f5

Furthermore, I seemed to have to run the install_requirements.sql manually from dockerfile/ in order to get search to work at all.

I don't think this is really supported anymore; at least, no one at the team is regularly using it. I think we should remove the forge page and change https://github.com/rust-lang/docs.rs#running-tests so it doesn't point there (that section is pretty out of date as well - it confuses "no docker-compose at all" with "no docker-compose for the web server").
