feat: Add a new input flag to avoid commenting on stacks that have not changed.

[drew-rsk]

Adds a flag to allow users to skip comments for stacks that have not changed.

@drew-rsk overall the PR looks good! The only thing missing is adding the new input property to the action metadata here

cdk-diff-action/.projenrc.ts

Line 23 in 69475f7

actionMetadata: {

I'm a little hesitant to add this feature as is because I'm worried that it creates a scenario where something could fail to process and the user would think that it was because the stack had no changes.

What would you think about having a single summary comment that has info on what stages/stacks were processed? It could just be a single comment saying that stacks x,y,z had no changes.

Q1: Yeah that'd be a good step and possibly sufficient for my team's development purposes. How can I play with my changes as they are, or any other PR's changes, as a way to manually inspect the results?

Q2: I propose leaving this PR as is and working up an independent one that does what you suggest over hacking this one into a different functional solution. How does that plan suit you?

You can pin an action to a branch if you want to test. Something like this should work.

I'm not sure what you are asking here. I'm not comfortable merging this PR as is because I think we need to have some kind of indication that all stacks were processed.
