'No Documentation found' popup is shown(instead of the docs) when `Ctrl + Q` is pressed for well-known functions

[SergeyMosin]

Describe the bug No Documentation found. popup is shown(instead of the docs) when Ctrl + Q is pressed while a function such as IO.inspect("foo") is under the caret.

To Reproduce Steps to reproduce the behavior:

1. Create a project
2. Insert/type IO.inspect("foo") where it is allowed
3. Place cursor/caret inside the inspect function name
4. Press Ctrl + Q
5. No Documentation found. popup is shown

Expected behavior When Ctrl + Q is pressed while cursor/caret is place inside a function name, documentation for that function should be shown.

Screenshots Ctrl + Q when inside inspect

Ctrl + Left Click

Ctrl + Q when inside IO (works as expected)

Reader mode works, so it must be parsing somehow.

Thanks for the report, it's definitely a very useful feature so let's get it sorted.

[joshuataylor]

I believe this might be due to having multiple definitions for functions, and it isn't sure which it should use.

Perhaps we could have a way of determining if there are multiple definitions, and if there is only one docblock, show that? Or we could have a "known good" list for inbuilt, as we don't want to show the wrong docs as well.

Eg Enum.sort can display the docs, when within the module:

And it works for within the same module:

But Enum.map autocomplete DOES work:

Just not when multiple definitions.

I'll dig into it, would be great to get this solved.

I see now. I did not realize that I can get the docs by pressing Ctrl + Q while inside the drop-down, like the Enum.map example above. This is perfectly fine for me. Thank you for the great plugin.
