Adapt how the theme and docs are configured.

The loaders section of the config contains theme and docs components, each of which take a URI.

The default theme supplied by the mkdocs package, and the documentation served directly from the project directory. This is the default configuration...

[loaders]
theme = "pkg://mkdocs/default"
docs = "dir://"

The default theme as a .zip URL, and a local docs directory...

[loaders]
theme = "https://github.com/lovelydinosaur/mkdocs-theme/archive/refs/heads/main.zip"
docs = "dir://docs"

A theme downloaded locally, and a docs directory...

[loaders]
theme = "dir://theme"
docs = "dir://docs"

Both the theme and the documentation included in a single directory...

[mkdocs]
theme = "dir://docs"
docs = "dir://docs"
