Problem with escaped underscores in vim.lsp.buf.hover floating window

[jakubbortlik]

Thanks for the excellent plugin!

I've run into a problem when inspecting documentation for a Go function. The original docstring contains this text (shortened):

// ...
// Please refer to https://golang-jwt.github.io/jwt/usage/signing_methods/#signing-methods-and-key-types
// ...
func (t *Token) SignedString(key interface{}) (string, error) {

When I run vim.lsp.buf.hover() twice on the function and focus the floating window, the link is transformed to this markdown format: [https://golang-jwt.github.io/jwt/usage/signing\_methods/#signing-methods-and-key-types](https://golang-jwt.github.io/jwt/usage/signing_methods/#signing-methods-and-key-types) - notice the escaped underscore in signing\_methods

The default implementation of gx is able to navigate to the site correctly, while gx.nvim interprets the \ as a normal slash a tries to navigate to a non-existing site with signing/_methods.

It's no big deal, I don't often follow links from documentation floating windows, but do you think @chrishrb that this could be fixed? Thanks in advance!
