Update manual now stable can be installed with rustup

Browse source 
`rustup` can now install `rust-analyzer` for the stable tool-chain. This commit removes the note that `rustup` can only install for the nightly branch and adjusts the command.

I also added a note on how to find the path to the `rust-analyzer` binary when installed using `rustup`, and suggestions on how to work around it not being placed in `~/.cargo/bin`.

I thought it would be ideal to point everyone to use `rustup run stable rust-analyzer` to start `rust-analyzer`. That would make it trivial to switch to nightly however I could not get this to work in `nvim` therefore I left it as a suggestion at the end.

==== `rustup`
`rust-analyzer` is available in `rustup`, but only in the nightly toolchain:
`rust-analyzer` is available in `rustup`:
[source,bash]
----
$ rustup +nightly component add rust-analyzer-preview
$ rustup component add rust-analyzer

However, in contrast to `component add clippy` or `component add rustfmt`, this does not actually place a `rust-analyzer` binary in `~/.cargo/bin`, see https://github.com/rust-lang/rustup/issues/2411[this issue].
However, in contrast to `component add clippy` or `component add rustfmt`, this does not actually place a `rust-analyzer` binary in `~/.cargo/bin`, see https://github.com/rust-lang/rustup/issues/2411[this issue]. You can find the path to the binary using:
[source,bash]
----
$ rustup which --toolchain stable rust-analyzer

You can link to there from `~/.cargo/bin` or configure your editor to use the full path.
Alternatively you might be able to configure your editor to start `rust-analyzer` using the command:
[source,bash]
----
$ rustup run stable rust-analyzer
