Absinthe.Resolution.path_string/1 crashes if path includes a list

[mdg]

I have a patch for this one ready. Just submitting the issue for referencing from the PR.

Environment

• Elixir version (elixir -v): 1.16.2
• Absinthe version (mix deps | grep absinthe): 1.7.8
• Client Framework and version (Relay, Apollo, etc): n/a

Expected behavior

Expected Absinthe.Resolution.path_string/1 to always return a list of strings and not raise a FunctionClauseError

Actual behavior

If the query path contains a list, the path value list contains an integer for the node in the path that is a list item. The fn passed to the map matches on maps and a FunctionClauseError is raised when it gets to the integer. case statement fails with a FunctionClause

Relevant Schema/Middleware Code

Schema has to include a list upstream from the field being resolved when path_string is called.

absinthe/lib/absinthe/resolution.ex

Lines 238 to 246 in 3d0823b

	def path_string(%__MODULE__{path: path}) do
	Enum.map(path, fn
	%{name: name, alias: alias} ->
	alias || name
	%{schema_node: schema_node} ->
	schema_node.name
	end)
	end

[mdg]

This function doesn't actually have any documentation so it's not entirely clear how it's different from path/1. In attempting to add the documentation, it's unclear how to describe what it does.
