This commit:
1. Removes the header from the Data Driven Forms wizard
2. Adds padding around the in-page wizard so it is visually consistent
with the images table
3. Refactors the images table header into a re-usable component that is
now used in both the images table and the wizard
4. Allows the repositories table to fill the available vertical space in
the wizard
5. Adjusts the package dual list selectors so that they fill the
available horizontal space in the wizard
A documentation button, which contains an external link to the
official documentation, appears several times throughout the frontend.
Currently, the code for the documentation button is copy/pasted where
needed. Adding a form component for the documentation button allows code reuse
and improves readability in the code that calls it.
Because this component is used by the LandingPage, ImagesTable, and
ImageWizard it has been placed in a new directory,
`src/Components/sharedComponents` which is at the same level as these
directories.
