Run CI only on line/centraldogma

Motivaiton:

I found that CI builds are run on the forked repositories.

https://github.com/ikhoon/centraldogma/actions

Modifications:

- Add `github.repository == 'line/centraldogma'` condition for CI builds

Result:

CI builds no longer run on the forked repositories.
