bug: Line continuations for aliases from LuaCATS Annotations is not parsing

[ColinKennedy]

Did you check existing issues?

• I have read all the tree-sitter docs if it relates to using the parser
• I have searched the existing issues

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

tree-sitter 0.22.5

Describe the bug

Possibly related to - #12

There's an example of line continuations in the LuaCATS Annotations page that this parser doesn't currently handle. It's under @alias's examples, here: https://luals.github.io/wiki/annotations/#alias

---@alias DeviceSide
---| '"left"' # The left side of the device
---| '"right"' # The right side of the device
---| '"top"' # The top side of the device
---| '"bottom"' # The bottom side of the device
---| '"front"' # The front side of the device
---| '"back"' # The back side of the device

This same tree parses as expected with llscheck, which further leads me to believe it's a bug.

Steps To Reproduce/Bad Parse Tree

Make a file with

@alias DeviceSide
| '"left"' # The left side of the device
| '"right"' # The right side of the device
| '"top"' # The top side of the device
| '"bottom"' # The bottom side of the device
| '"front"' # The front side of the device
| '"back"' # The back side of the device

Then run tree-sitter parse that_file.lua
