Enable Enter/Return key to apply current Filter [Fixes #2421]

[Qashworth]

Description

This PR wraps the button in a form to handle Enter / 'Return' keypress events within the .component instead of requiring users specifically click the 'Apply' Button discussed in #2421

Background

Currently users need to explicitly press the 'Apply' button to submit filtered searches. This is an attempt to handle Enter/Return Key presses within the Filtercollapse.js component instead of requiring users specifically click the 'Apply' Button. I've wrapped the InputGroup in a Form, removed the 'Apply' button's onClick event, added the "submit" type to the 'Apply' button, and added a function to handle when the onSubmit event is fired.

This should allow the 'Apply' button to maintain it's ability to be clicked as well as fire when the Enter/Return Key is pressed.

How to test

• Check out this branch locally & start app
• Open a Cube list
• Click the 'Filter' option
• Type desired search criteria into the Filter input
• Click the Enter / Return key on your keyboard
• The Cube list should be filtered accordingly

Additional Notes:

My first PR here (of hopefully many more) please be gentle! 😂

Thanks @lunakv, I'll be sure to format future PR's accordingly!

I did just notice that I failed to add the Form component to the other imported components for FilterCollapse.js in this PR, which breaks List view entirely:

What would be the best way to go about including that component? Reverting this PR, opening a new one, some other third thing?
