Add FormHeader and update helm form title to be reactive

[rohitkrai03]

Fixes: https://issues.redhat.com/browse/ODC-4229

Analysis / Root cause: Latest changes to helm install/upgrade form needed the subtitle for the form to change when user toggle between form view and yaml view. but the page title for the form was at page level and had no idea of the form context.

Solution Description:

• Created a new reusable FormHeader component that abstracts the page title logic and implements the current design properly.
• Brought the header at form level to make it reactive to the form context,
• Added new unit tests for the form component.

@parvathyvr @beaumorley @serenamarie125 Updated the grid layout for the form based on our conversation from yesterday's Helm meeting so that the form can acquire more real estate than before. It follows the same breaking points as the OLM form now. Please take a look at the below gif. cc: @christianvogt
