fix(neogen): keymap for type-aware automatic comment generation

[CMOISDEAD]

Keyboard shortcut (leader + a + CR) for automatic comment generation did not correctly detect element type (function, class, etc.). This commit fixes the bug so that the shortcut correctly detects element type and generates the appropriate comment.

📑 Description

The "keymap" (leader + a + CR) that triggers the automatic neogen generation does not work and throws an error message saying "current type is not supported".

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.
