Bump semantic-release to 23.1.0, and update our configuration file(s)

[HonkingGoose]

Describe the proposed change(s).

Semantic Release v23.1.0 has this change:

add main branch to default release branch config

I think this means we do no longer need to explicitly define the main branch, in this file?

renovate/.releaserc.json

Lines 93 to 96 in 8bbde23

	"branches": [
	{
	"name": "main"
	}

Maybe there are other Semantic Release config files that we should update, that I'm forgetting to list. 😉

Context:

• add "main" as alternative default branch semantic-release/semantic-release#1581
• Semantic Release docs, configuration file
• Semantic Release v23.1.0 changelog

we need to wait until we're using node v20 on CI, so semantic release v23 is still blocked
