[question]: Best practices for synchronizing versions in a two-branch prerelease workflow

[hydrosquall]

Describe the bug

The documentation for auto shipit recommends

To update the latest stable version simply merge your pre-release branch into your baseBranch.

A downside to this approach is that your long-lived prerelease will not have its version bumped, so it is now behind the stable branch.

(For example: This commit was created on stable)

• https://github.com/vega/vega-tooltip/commit/8ca292963c22ebc8699490313f11c05cdd7eb6d7

However, it was not applied to our long-lived pre-release branch, next, so our pre-release branch is now behind.

• https://github.com/vega/vega-tooltip/blob/b815153965f6f23d0240c99abf18ee86cbdc81e6/package.json#L3

Which would be the recommended way to keep a perpetual "prerelease" branches in sync with stable?

1. Manually create an additional PR after merging next -> stable to synchronize the versions in both places
2. Any time after next -> stable is merged, manually reset next to the head of stable
3. Come up with some sort of custom plugin to synchronize the branches automatically
