table literals with descriptions

I expect something like this or something similar to this to work but it doesn't
also when I e.g. split it up onto multiple lines
```lua
---@field cat { ["name"]: string # the name of the cat, ["age"]: integer # the age of the cat }
```
everything is working fine without the descriptions

Reproduce the reported LuaLS annotation with a table literal containing field descriptions, including the multiline form. Start by tracing how this annotation is parsed; done means both the shown single-line and multiline forms are accepted without breaking the existing form without descriptions.
