Dependabot automerge - automatically merge minor changes too

[mcm1957]

Currently our standard setup for dependabot automerge is configure as following:

update change - merge into devDependencies and (prod-) dependencies
minor change - merge into devDependencies but NOT into (prod-) dependencies
major change - do NOT merge at all

As discussion at telegramm (near https://t.me/ioBroker_development/31787) shows that almost all dependencies are configured using '^m.b.u' syntax. This way any minor update is installed at user systems whenever a new minor version exists and is used by at least one npm package. So ist does not realy seem to provide any benefit to require the devs to manually trigger such merges at adapetr directory.

SUGGESTION:
merge update and minor changes for devDependencies and (prod-)dependencies automatically (if tests succeed)
do nor merge major changes automatically (= no change)

Please review / discuss.I can provide a PR ich change is accepted. Feel free to assign to me.

While I agree, I really want to avoid ~a.b.c versions getting auto-updated to a different minor version without the dev being involved, as preventing this is the sole reason for the ~ specifier. If we can avoid this, go for it.

Absoliutly my oppinion too.
If ~cannot be expluded from automatic merge, we should leave it as it is.

I'll check as soon as I have time :-(
