fix: nil problem when jump to location when tab drop is set as jump_type (#2760)

* feat(lsp_definitions): adding `tab drop` as `jump_type`

* feat(lsp-jump-types): `tab drop` for LSP features

Now, you're able to use `tab drop` as `jump_type` for these LSP
features: references, type definitions, definitions an implementations.

* fix(docs): reordering `tab drop` option

* feat: generate docs

* fix: nil problem with `vim.uri_to_fname`

* fix: removing warning about `file_uri` variable not being used
