Last updated date appears to be incorrect

Description:
As the excerpt from the log below shows, I have a pull request that is identified as having been updated within the past several days even though the last update I can see is nearly one year ago.

[#514] Pull request #514
  [#514] Found this pull request last updated at: 2024-10-15T01:53:46Z

Action version:
v9

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Repro steps:
I am unsure how to reproduce this issue with a fresh repository, but here is an example of a run of this action that exhibits the problem.
For example, look at pull request 512.
It has not been updated in more than a year, but the action seems to think it was updated within the past several days.

Expected behavior:
The correct date of the last update should be identified.

Actual behavior:
The date of last update is not identified correctly.

I do see the updated_at date returned by the API is within the past several days, so I assume this is the root of the issue, but I don't see any user-facing updates visible. No commits pushed on the corresponding branch, no comments, no labels changed, etc.

Yep, running into this with a bunch of stale PRs on my repo too. For some reason a bunch of them got unmarked as stale 3 days ago. (Appears this may be to do with the base branch getting force-pushed???)
