ci: enable PR duplicate packages check

[ocavue]

Changes

We have disabled duplicate-threshold in e18e/action-dependency-diff (by setting it to a large number 100, instead of the default value 1). This PR re-enabled it.

Why we disabled it?

If we enable duplicate-threshold, the previous version of e18e/action-dependency-diff will emit all duplicated packages in the pull request comments. In the astro repo, that’s 200+ packages in total. An example bot comment is shown below:

ocavue-forks#36 (comment)

This information in the comment is too verbose and not useful at all. I guess that's why we disabled it.

Why enable it now?

In the latest e18e/action-dependency-diff v1.7.x, I've contributed a feature that changes duplicate-threshold to only scan the changed dependency in a pull request.

For example, PR #17450 introduced some duplicated package. Now the CI would comment the following content:

ocavue-forks#38 (comment)

The bot comment is much more useful now.
