Throws error on empty path in resource location

[AmericanBagel]

Mecha throws an error when a resource location with no path is used, such as the following:
@function foo:bar

data modify storage foo: mydata set value []

This is the error:

ERROR  | mecha  Expected quoted_string or string but got invalid ': mydata set value []'.
       | src/data/foo/functions/bar.mcfunction:1:24
       |      1 |  data modify storage foo: mydata set value []
       |        :                         ^^^^^^^^^^^^^^^^^^^^^

When it's changed to foo:bar, it works just fine. I'm not at all familiar with the codebase, but I did some quick searching. In other contexts, this would throw an error. However, data storage is one of the few cases (next to functions named .mcfunction) which can apparently do this without issue in Minecraft. However, Mecha takes the brigadier resource object, reads that it specifies minecraft:resource_location, and passes it off to AstResourceLocation, which seems to assume a non-empty path.
