Add syntax highlighting and LSP (erlang_lsp) for Erlang (#7093)

Browse source 
This pull request implements support for the [Erlang
Language](https://erlang.org/).

**It adds:**

* [tree-sitter-erlang](https://github.com/WhatsApp/tree-sitter-erlang)
grammar
highlights (Licensed under Apache-2 from WhatsApp which is compatible
with Zed licensing model), folds and indents
* Erlang file icon based on the [official
one](https://www.erlang.org/doc/erlang-logo.png)
* [erlang_ls](https://github.com/erlang-ls/erlang_ls) support

Fixes https://github.com/zed-industries/zed/issues/4939, possibly a
duplicate of https://github.com/zed-industries/zed/pull/7085 with more
features. Suppose @wingyplus wants to join efforts here.

**To complete (out of scope for this PR):**

* Support for the ELP language server from WhatsApp. CC @robertoaloi
* Better indentation handling, need something like
`indentNextLinePattern` in VS Code
