try to use treesitter instead

[teto]

trying to use treesitter nodes to identify the requests, method etc instead of relying on weak heuristics.

The issue I have at the moment is the root node appears as a "document" https://github.com/rest-nvim/tree-sitter-http/blob/2c6c44574031263326cb1e51658bbc0c084326e7/grammar.js#L15 but I can't find it anywhere in the treesitter playground

TODO:

• [ ] GET remove or ditch support for this syntax ?

/api/users?page=5 HTTP/1.1
Host: reqres.in:443

• [ ] support of curl_raw_args ?
• [ ] parse_url had if config.get("encode_url") then target_url = utils.encode_url(target_url) end, do we still need this ?
• [ ] check one can set http_version as in older version
• [ ] remove regex to capture the "script" part and instead retreive the content of the "internal_payload" node (problem is that currently the "internal_payload" node is full of errors)
• [x] support external body
• [ ] support embedded body

we already have variables

• [x] should be able to list requests in a file
