bug#61312: Patch for eglot: scala LSP binary name

[skykanin]

Hello,

It seems that eglot expects the scala metals LSP server binary to be named 
`metals-emacs` instead of `metals`. The included patch fixes this behaviour. At 
least in the nix package manager the `metals` binary is simply call 'metals'. 
However if other package managers distribute an alias for the binary as 
'metals-emacs' as well we could instead do something like:
```
(scala-mode . ,(eglot-alternatives '("metals" "metals-emacs"))
```
