The tree-sitter-cli expects all tests to be in a test dir within the
project root.

These tests broke at some point and were never updated. As the new
output doesn't seem incorrect, I'm just updating the expected output to
match what the grammar currently produces.

tree-sitter language repos have a specific layout and package.json which
is defined by the tree-sitter project, and enforced by the
tree-sitter-cli. Most of the changes in package.json are from the
tree-sitter-cli updating it to conformance

Updating tree-sitter has resulting in output changes due to improved
error handling in the tree-sitter parse. The new output is much more
informative when parsing errors occur compared to previous versions.

It useful to be able to query for actual string fragments between string
deliminator. The (stringFragment) now makes it possible to break down
strings into their different fragments and interpolations.

There's no need to use a regex to detect types, we can detect using just
the syntax tree. Using a regex results in unnecessary false-positive
matches.

tree-sitter doesn't like it when you use non-static functions as they
may collide with function names in other grammars. There's no reason not
to make this function static as it not used anywhere else.

Fields make it much easier to write smart queries using the grammar, as
things like detection of default values can be included in the grammar
via field, removing the need for queries to handle those detections
themselves.
