Outdated documentation using archived EVEREST repository

[roliveira]

What happened? (You can include a screenshot if it helps explain)

The current documentation still has artifacts from the standalone and now archived EVEREST repository.

• Editing from the rendered documents takes the user to the archived EVEREST repository

ert/docs/everest/conf.py

Lines 121 to 125 in 735ea0e

	html_theme_options = {
	"source_repository": "https://github.com/equinor/everest/",
	"source_branch": "main",
	"source_directory": "docs/source",
	}

• The installation intructions are still using the archived EVEREST repository

ert/docs/everest/installation.rst

Line 14 in 735ea0e

$ pip install git+https://github.com/equinor/everest.git

• The development chapter points to the archived EVEREST repository

ert/docs/everest/index.rst

Lines 53 to 54 in 735ea0e

	Code in GitHub <https://github.com/equinor/everest>
	Issue tracker <https://github.com/equinor/everest/issues>

What did you expect to happen?

Update the links and instructions with the archived EVEREST repository to use the ERT repository.
