Install crispy forms

[AdrianDAlessandro]

Description

This goes part of the way to addressing #68 but does not completely close the issue since there is much more that can be done with it.

All this does is install crispy forms and use it to filter the existing form to get some bootstrap5 styling.

Type of change

• Documentation (non-breaking change that adds or improves the documentation)
• New feature (non-breaking change which adds functionality)
• Optimization (non-breaking, back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)
• Breaking change (whatever its nature)

Key checklist

• All tests pass (eg. python -m pytest)
• The documentation builds and looks OK (eg. python -m sphinx -b html docs docs/build)
• Pre-commit hooks run successfully (eg. pre-commit run --all-files)

Further checks

• Code is commented, particularly in hard-to-understand areas
• Tests added or an issue has been opened to tackle that in the future. (Indicate issue here: # (issue))

LGTM. Just 'crispy'fying the existing boot form.

LGTM!

Looks good. I'm going to take the liberty of bootstraping the submit button as well and then merge this. I'm going to close #68 as this is totally fine for our purposes.
