Update L1 configuration in Run 2 eras to match customisation functions

[mark-grimes]

Title says it all. Has no change whatsoever unless one of the Run 2 eras is active.

I'm about to put in another request on the same lines, but I've split it off to limit the number of signatures required. I'll note the PR number here once it's been submitted.

The other pull request is #10172. Each incrementally brings the eras and customisations into line but aren't dependant on each other.

Closing this because it's out of date now, and everything is included in #10187. I'm about to push the most recent changes to there, so no need for this PR.
