ruby: Check if `solargraph` exists in `$PATH` or is configured (#10835)

This fixes #9811 by checking for the `solargraph` binary in the `$PATH`
as it's setup in the project shell.

It also adds support for configuring the path to `solargraph` manually:

```json
{
  "lsp": {
    "solargraph": {
      "binary": {
        "path": "/Users/thorstenball/bin/solargraph",
        "arguments": ["stdio"]
      }
    }
  }
}
```

## Example

Given the following setup:

- `ruby@3.3.0` used globally, no `solargraph` installed globally
- `ruby@3.2.2` used in a project, `solargraph` installed as binstub in
`$project/bin/solargraph`, `.envrc` to configure `direnv` to add
`$project/bin` to `$PATH

Which looks like this in practice:

```shell
# GLOBAL
~ $ ruby --version
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [arm64-darwin23]
~ $ which solargraph
solargraph not found

# IN PROJECT
~ $ cd work/projs/rails-proj
direnv: loading ~/work/projs/rails-proj/.envrc
direnv: export ~PATH
~/work/projs/rails-proj $ ruby --version
ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin23]
~/work/projs/rails-proj $ which solargraph
/Users/thorstenball/work/projs/rails-proj/bin/solargraph
```

The expectation is that Zed, when opening `~/work/projs/rails-proj`,
picks up the local `solargraph`.

But with **Zed Stable** that doesn't work, as we can see in the logs:

```
2024-04-22T10:21:37+02:00 [INFO] starting language server. binary path: "solargraph", working directory: "/Users/thorstenball/work/projs/rails-proj", args: ["stdio"]
2024-04-22T10:21:37+02:00 [ERROR] failed to start language server "solargraph": No such file or directory (os error 2)
```

With the change in this PR, it uses `rails/proj/bin/solargraph`:

```
[2024-04-22T10:33:06+02:00 INFO  language] found user-installed language server for Ruby. path: "/Users/thorstenball/work/projs/rails-proj/bin/solargraph", arguments: ["stdio"]
[2024-04-22T10:33:06+02:00 INFO  lsp] starting language server. binary path: "/Users/thorstenball/work/projs/rails-proj/bin/solargraph", working directory: "/Users/thorstenball/work/projs/rails-proj", args: ["stdio"]
```

**NOTE**: depending on whether `mise` (or `rbenv`, `asdf`, `chruby`,
...) or `direnv` come first in the shell-rc file, it picks one or the
other, depending on what puts itself first in `$PATH`.

## Release Notes

Release Notes:

- Added support for finding the Ruby language server `solargraph` in the
user's `$PATH` as it is when `cd`ing into a project's directory.
([#9811](https://github.com/zed-industries/zed/issues/9811))
- Added support for configuring the `path` and `arguments` for
`solargraph` language server manually. Example from settings: `{"lsp":
{"solargraph": {"binary":
{"path":"/Users/thorstenball/bin/solargraph","arguments": ["stdio"]}}}}`
