Use `djlint` to pre-commit our django templates

[yuvipanda]

Currently they are being linted and autoformatted as HTML, leading to errors like this:

Instead, djlint should be used for all files inside the templates directory: https://www.djlint.com/docs/integrations/

- [ ] Update  `.pre-commit-config.yaml` to run the `djlint` hook on all the files in the templates directory
- [ ] Validate that it works

Definition of Done

• [ ] there is a pre-commit hook that runs djlint
• [ ] errors are not rendered as html anymore
