[INFRA] Set up Github Actions

[ansjcy]

Is your feature request related to a problem?

Currently we don't have proper Github Actions set up for query insights dashboards plugin.

What solution would you like?

• MVP: We should have automated actions to build, test and release this dashboard plugin.
• Github actions for tagging
• Github actions for backport
