fix: bring more_examples up to date and minor formatting fixes in docs

[gvwilson]

1. Minor typography fixes in CHANGELOG.md, CODE_OF_CONDUCT.md, and CONTRIBUTING.md.
2. Switch from app.run_server to app.run in more_examples/*/*.py.
3. Update use of Dash Mantine Compnents in more_examples/demo_stock_portfolio_dmc/app.py.

Note: filters do not appear to work correctly in more_examples/convert_units but that could be operator error - guidance would be appreciated.

Q: some of the examples in more_examples needed extra packages (listed below). Where should these be recorded?

• dash-bootstrap-components
• dash-iconify
• dash-mantine-components
• pandas
• yfinance

I think as far as examples, what do you think about having them written above the code and commented out?

I'm not sure the examples are relevant with the docs though.

@AnnMarieW, what are your thoughts?

[AnnMarieW]

Actually the docs and the more_examples folders were created before docs were available in the dash docs. All the relevant examples have been moved over there.

It might be better to delete all these files and examples as they are no longer maintained.

[gvwilson]

I am 100% in favor of deleting stuff - can you please confirm that I should close this PR and rm -rf the docs and more_examples directories? Anything else we can get rid of? In particular, are we maintaining/documenting DAG for languages other than Python?

[AnnMarieW]

There are a couple Medium articles that link to apps here. I think it would be good to keep those and add a requirements.txt and a README.md that links back to the article.

I can do that if you like.

[gvwilson]

Thanks @AnnMarieW - can you please send me the links to the Medium articles and I'll update this PR? I feel like I already ask enough other favors of you (and may need to ask more to get this stuff published).

Here’s the article with the link to an app here: https://medium.com/plotly/announcing-dash-ag-grid-fbb4a1c83e62

This one is linked to my dash-ag-grid-examples repo, so it’s not affected : https://medium.com/plotly/announcing-dash-ag-grid-fbb4a1c83e62

[gvwilson]

thanks everyone - I've updated the PR. Please let me know if it looks OK and I'll merge it, then get back to trying to figure out #355 and how to publish new versions of this package.

[BSd3v]

@gvwilson, before you work with that PR, the issue for splitting and refactoring needs to be addressed.

💃

[AnnMarieW]

@gvwilson are you going to delete the more_examples folder and the unused apps in the docs folder in a separate PR?

[gvwilson]

I can do, but I don't want to break the link in your Medium post - if you're able to edit the latter, I can move the example somewhere else?

[AnnMarieW]

No problem - I'll do a new PR to remove the unnecessary files.
