Jamie Tanna 2d239d2cc1 docs: explicitly document depTypes each manager supports (#42142)
* docs: explicitly document `depTypes` each manager supports

A long-standing question we receive is "what `depTypes` can I match
against in my project".

Although the best recommendation we usually have is "check the
`packageFiles with updates" log line (as a very key log line for users),
we can go one step further and try and create a stronger contract.

To do this, I've used Claude Sonnet 4.6 to work through the codebase,
determine areas that a `depType` is set in a manager (statically or
dynamically) and generate a structured, typed, means to document how
they're used.

Through a few iterations of the process, and attempts at human-written
documentation, we've settled on:

- prioritising autogenerated documentation (for humans to read) to note
  what `depTypes` are known, and what they are
- `knownDepTypes`, to describe any known, static, `depType`s and their
  human-readable meaning
  - with the `prettyDepType`, if used
- `supportsDynamicDepTypesNote`, to add a Markdown note to the generated
  documentation

While here, we also:

- make sure to note this in the "adding a new package manager"
  documentation
- remove any hand-written references to `depTypes` in each manager's
  documentation page
- correct the Gleam `depTypes`
- make sure to use the `knownDepTypes`'s `prettyDepType` definition if
  we know it, for a given `depType`

The descriptions have been generated by Claude Sonnet, with some
human-written tweaks where appropriate.

* fixup! docs: explicitly document `depTypes` each manager supports

* docs(manager): display `depTypes` documentation if none present

For consistency, and to make it more explicit.

Extracts all Docker images from the image and features properties in these files:

  • .devcontainer.json
  • .devcontainer/devcontainer.json

It extracts some known versions of the features, like node and python.

The devcontainer manager does not support build.dockerFile or dockerComposeFile values as these are covered by the dockerfile and docker-compose managers respectively.
