ci: reduce the running of ci

[uiolee]

I guess it's not always necessary to run ci.

1. linter and tester only need to be executed when the code or environment changes
2. dependabot causes ci to run twice
   

What does it do?

1. add paths filter. only run ci when the code changes.
2. add branches filter. only run ci in specified branches.

How to test

git clone -b ci https://github.com/uiolee/hexo.git
cd hexo
npm install
npm test

Did #5153 cause the test to fail?
