Subject: [PATCH] docs: add hint on configuring custom filetypes (#5552)

I thought that this functionality was not possible but there's actually
an API for it. This seems like a useful place for others to find more
information on it.

+#### Using an existing parser for another filetype
+
+For example, to use the `bash` tree-sitter to highlight file with
+`filetype=apkbuild`, use:
+
+```lua
+vim.treesitter.language.register("bash", "apkbuild")
+```
+
+The `bash` tree-sitter must be installed following the usual procedure [as
+described above](#language-parsers).
