The suggested copy paste attribute path is often wrong as it depends on the individual repository setup that dream2nix doesn't control.
Instead now simply hint to `nix run` the .lock attribute
This allows updating the lock file via `nix run .#{package}.lock` instead of ` nix run .#{package}.config.lock.refresh`
This is better as it's shorter, and the keyword `lock` is widely understood to lock dependencies.
For many users not having a snapshot date is a valid use case.
Also many users will expect their lock file to be updated to the latest dependency versions via a nix run .#package.config.lock.refresh. so it can be the default behavior.
When you had a pip git requirement such as `git+https://github.com/OCA/maintainer-tools`, `fetch_pip_metadata` was failing with:

- nixpkgs-overrides are not lazy enough. They can lead to eval failures thrown in nixpkgs despite not being enabled. Therefore we better use the `import` as an enable mechanism instead of the `enable` option.
We keep the enable option to allow for users to disable the override module via mkForce
* Make pip lock script use its own python version
To make the lock script independent of the python version used in the
user's project, it needs to use its own python environment. This was
already the case for the mitm proxy, but not yet for the lock script
itself. This commit ensures that the lock script uses its own python
environment, independent of the user python version, and shares it with
the mitm proxy.
* Fix IOKit dependency in htop example
* Add hash for git based packages
* Support install git dependencies
* Add test for pip with git dependency
* Update lockfiles for python example projects
This does not change any of the hashes or versions, just adds the type:
"url" property.

- add flake-module.nix
- remove custom logic to find the repo root
- use findRoot script to find repo root
- use gitMinimal instead of git
- use separate python version for lock script than the python version to lock for. This prevents rebuilds and allows defining a standalone fetchPipMetadata package
