RFC: change release cadence

[nlopin]

Context

At the moment, Wave releases a new version on every pull request merge.

Recently, the number of pull requests has increased and often we merge several PRs within one day. This means that sometimes we publish several minor versions per day. It makes a lot of noise and it is harder to spot what change has happened.

Proposal

Implement "one day - one release" policy. That means that releases are scheduled (e.g. midnight every day) and the release contains all the merged PRs on the day of release.

• if I merged any number of PRs today, the release will take place 23:59 the same day containing both changes merged
• if no PRs were merged, no release

Risks

• We may want to release a new version as fast as possible. Solution: we trigger release manually or using manually triggered Github Action

I think I overlooked something, because we do have some kind of batching already

The only scenario I'm thinking of which can be problematic is if we need a release and use it without waiting a day, but I suppose it's not common to have that sense of urgency, and we can also deploy manually if that's the case. Sounds good to me! 👍🏻
