Release for Lotus v1.28.0-for-mainnet-upgrade

[BigLep]

Done Criteria

1. There is a tagged release that Lotus v1.28.0 can depend on that has the F3 functionality needed for Lotus v1.28.0 stable release. This will be all the functionality for nv23.
2. There is a PR to Lotus master depending on this version

Items in scope

Generally this corresponds with all the functionality in:

• https://github.com/filecoin-project/go-f3/milestone/1
• https://github.com/filecoin-project/go-f3/milestone/2

Specific items that must be in here that aren't completed yet at the time of this issue being created include:

• TBD - add items here.

Notes

I know the release is trivial, but I created this issue so:

1. it could be linked from the Lotus v1.28.0 release issue. I didn't want the Lotus issue to be tracking individual F3 items. It should just be waiting for the go-f3 release.
2. Make it clear that there is the open-a-depenency-bump step that needs to be done after the code is merged
