Distinguish between methods and functions

Is your feature request related to a problem? Please describe.
I want a way to distinguish between methods and functions in JavaScript and other languages.

Describe the solution you'd like
I'd like:

			goto_next_start = {
				["]k"] = "@class.outer",
				["]m"] = "(method_definition) @function",
				["]f"] = "@function.outer",
				["]b"] = "@block.outer",
			}

to work (I realize I'm not specifying javascript for ]m but I was just testing it out before cleaning it up.

Describe alternatives you've considered
None

Additional context
I'd like to do something like this eventually:

			goto_next_start = {
				["]k"] = "@class.outer",
				["]m"] = {
                                   javascript: "(method_definition) @function",
                                   java = "(method_declaration) @function",
                                   "@function.outer"
                                }
				["]f"] = "@function.outer",
				["]b"] = "@block.outer",
			}

So that I can correctly move from method to method in the languages I most often work with and fall back to the more generic solution when an override isn't defined.

Start by tracing how the goto_next_start configuration is read and how Tree-sitter captures such as @function and (method_definition) are handled. Confirm that language-specific method queries can override the generic function query for JavaScript and Java, while retaining the generic fallback.
