We are starting to enforce code styling with black, prettier and djhtml in Hypha.
The changes are not big but will touch _many_ files. See PRs below.
We suggest other organisation run `pre-commit run --all-files` on their code base before trying to merge in changes after PR #3547 are merged in to main.

> Add black and prettier check to lint
>
>
> \- Add black, djhtml, prettier
> \- Add precommit
>
>
> This PR add configurations f…or black, djhtml and prettier.
>
> \- black is used for formatting python files
> \- djhtml for formatting html files. Use \`{# fmt: off #}\` and \`{# fmt: on #}\` where needed.
> \- prettier for formatting of sass,css,yml and js files
>
> Note: prettier picks up some of it's config from \`.editorconfig\`, so it's updated appropriately
>
> Formating of mardown files, minified or vendored js files are ignored.
>
> Formatting used off-the-self rules for better consistency with the community as large.
>
> The formatting is not applied to all the files as it will introduce a lot of merge conflict with
> current PRs, instead \`pre-commit\` config is provide which can be installed by \`precommit install\`
> locally. It will format only the modified files in the PR/commits.
>
> Once majority of the current active PRs are either rebased & formatted using precommit or merged, we can
> run the \`make fmt\` on the full repo and activate additional prettier and black checks in our lint rules.
>
> The modified sass files fixes the eslint error that would came up if we were to apply the prettier formatter on them.
>
> Fixes #3500
