Reduce `tools/publish-crates.sh` to only publish `bindings` and `sdk`

[bfops]

We really only need to publish the module bindings and rust SDK crates; we don't actually need to publish the CLI or standalone server crate, we just do it because they're in there among our other crates.

Really, we just need to publish the crates that are used by module code and client code (which is what we do for e.g. C#).

This would reduce the number of crates we have to publish from 32 to 11. And the server-related crates tend to be slower to build as well.

I guess doing cargo install spacetimedb doesn't really work anyway because we have many other things that need to be installed as well? Our install process doesn't really fit well with how cargo installs packages anyway. We already killed homebrew support mainly because of this and I think it seems reasonable to no longer support cargo install spacetimedb as well. @cloutiertyler what do you think?

Upgraded to a P1 so that we hit this during standup because we don't look at P2s during standup
