The release note generated by action-gh-release includes older changes than the selected version

[ffjlabo]

What happened:

When I use action-gh-release, some older changes exist.

For example, I released v0.46.0 from v0.45.4. I expected the release note to include changes from v0.45.4 to HEAD commit, but there were some changes created at older than v0.45.4.

#4775 (comment)

Maybe it looks like changes from v0.45.0 to HEAD commit because the last one is the next to the merged commit for v0.45.0.

What you expected to happen:

We hope to include the correct changes like from v0.45.4 to v0.46.0.
