Mnt/annotate keyboard methods

[welli7ngton]

• MNT: Annotate all keyboard methods
• style: set double quotes as default quoting, before had no default quoting and
  some methods were using single quotes and some were using double, my formatter (black)
  changed all the quotes to double quotes, and changed the indent of methods (
  find_multiple, find, find_until, find_all, find_text,
  click, click_relative, double_click_relative,
  triple_click_relative, right_click, right_click_relative,
  find_app_element
  )

Sorry for the size of the PR, guys, but had some 'automate' changes because of the black formatter and the keyboard session is pretty big ;)

@welli7ngton great work!

Just an observation, I noticed that in some keyboard methods, the parameter type or return type was missing:

• type_key
• type_keys_with_interval
• type_keys
• copy_to_clipboard
• key_enter
• Some methods that use alt_<key>
• Some methods that use control_<key>

Could you please revisit these methods to validate if any adjustments are needed?
