[improvement][ci] make sure each merge with the chart version promote.

[matrixji]

Some basic rules needed to add to ci:

• if things are changed under the charts folder, the version field in charts/devlake/Chart.yaml should be promoted, e.g: v0.14.5 -> v0.14.6, v0.14.5 -> v0.15.0
• the chart and the devlake version alignment: using the same major and minor version numbers, and could have different patch numbers. e.g chart version v0.14.5 for DevLake version v0.14.2
• each merge to master should be fast-forwardable and all commits need to squash to one before it merged

I'll add some initial CI actions to check it for PR, and initial some guidance for it.
