Feature Request: support other package managers rather than package.json (dependabot)

I've been using this action to automatically generate chagesets for affected packages with dependabot.

• workflow for automated changesets: https://github.com/ladesa-ro/domain/blob/0c06070a8495db0764dfb8b30c5c9e030c9ecc10/.github/workflows/dependabot-changesets.yml
• dependabot config: https://github.com/ladesa-ro/domain/blob/0c06070a8495db0764dfb8b30c5c9e030c9ecc10/.github/dependabot.yml

It's works fine for dependabot updates that are specific for node/bun projects, to be specific, the changes made to package.json.

But i've been using changesets and dependabot with a monorepo with bun + dotnet project. So, my monorepo has the following structure:

• defintions/package.json (bun)

• integrations/typescript/package.json (bun)

• integrations/dotnet

  • package.json (only for track version)
  • sln/project/project.csproj

the issue

when i got a dependabot update for integrations/dotnet/sln/project/project.csproj, mscharley/dependency-changesets-action do not detect the change, since the package.json do not have changed.

failed pr example: https://github.com/ladesa-ro/domain/pull/95

the proposal

i do propose an toggle feature that only works when the input detect-strategy: affected-package-dir is set.

with this option, if the subdirectory of a changesets project has some changes, it will be included, even if the package.json don't change

this is the current changeset status logic

https://github.com/changesets/changesets/blob/5ca6271a779b8f0414a29855ec21aa767a4fae16/packages/git/src/index.ts#L253-L287

Start with the affected-package-dir detect strategy and the referenced Changesets packages/git/src/index.ts range, then reproduce the linked failed PR using the .github workflow and dependabot configuration. Done means changes under a changesets project subdirectory are detected even when its package.json is unchanged, behind the proposed toggle.
