Update README

[project-delphi]

meaningful README with setup instructions:

Include setting up environment using conda for dashboards:

• python
• R
• installation of dependencies

[project-delphi]

We do need to fill this out properly so that it is useful

Looking good. Can we update readme with quarto install please?

[project-delphi]

https://quarto.org/docs/get-started/ , needs binary to be installed.

Probably affects #4

Let's get the README updated with simple opinionated flow to have running dashboard following clone.
