Allow detecting button element with bp_nouveau_get_members_buttons and bp_nouveau_get_groups_buttons

[sbrajesh]

Hi,
Currently, if 3rd party code wants to add extra buttons using the above 2 filters, they do not know if they should use button or anchor element.
These filters should pass the user passed $args to allow the detection of button element being used.

Please find the patch atatched.

Thanks @sbrajesh for your suggestion & patch. It looks good 👍

In 12979:

Pass expected arguments to Members/Groups Action button filters

To improve extensibility of the 2 functions BP Nouveau uses to generate these action buttons (bp_nouveau_get_members_buttons() & bp_nouveau_get_groups_buttons()), we are adding a new $args parameter to their corresponding filters ('bp_nouveau_get_members_buttons'& 'bp_nouveau_get_groups_buttons').

Doing so should help developers to have better information about the expected output for these buttons.

Props sbrajesh

Fixes #8497
