chore: delete unnecessary target branch filter in workflow trigger

[HansRobo]

Description

Abstract

This pull-request is deleting unnecessary target branch filter in workflow trigger

Background

When adding new features or refactorings that require multiple pull requests, the target branch is often set to something other than master.
There is no reason to exclude such cases from CI.

Details

This pull-request does not change any code.
So, no regression tests are executed.

The workflows below are not fixed because it makes sense to narrow down the target branch to master.

• .github/workflows/CheckBranchUpToDate.yaml
• .github/workflows/CheckLabel.yaml
• .github/workflows/Release.yaml

References

None

Destructive Changes
