Documentation-on-hover support for new OTP27 doc attributes

[NelsonVides]

Describe the bug

When hovering over function calls, documentation-on-hover shows information only if the documentation was written in the older edoc format, but not in the newer OTP27 doc attributes.

To Reproduce**

In the following code:

%% @doc this is edoc
edoc_dummy() ->
    ok.

-doc """
This is a doc attribute
""".
docattr_dummy() ->
    ok.

callers() ->
    ?MODULE:edoc_dummy(),
    ?MODULE:docattr_dummy(),
    ok.

Expected behavior

I'd expect both documentation types to display on hovering.

Actual behavior

edoc_dummy/1 hovering displays the edoc information, but docattr_dummy/1 does not.

Context

• ELP Version (output of elp version): elp 1.1.0+build-2024-08-05
• Editor used: neovim

@NelsonVides This is correct. Support for OTP 27 style EDoc is not added yet (but it's planned).
