ci(commitlint): disabled rules for subject-case

This will allow to start subjects from uppercase words.
Currently it fails on something like:
```
fix: Gitlab CI pipeline fixed
build: CMake sets wrong Synfig Studio/ETL versions
```

P.S. This change does not violate the standard. Discussion here:
conventional-changelog/commitlint#2141

P.P.S. Puppeteer did the same: https://github.com/puppeteer/puppeteer/pull/8091/files
