chore: deprecate "releases" branch by providing clear messaging

[BigLep]

This is being done as part of of #12374 . There are additional steps that need to be taken though per that tracking issue.

@rjan90 : feel free to take this one over or go a different path. The link to https://github.com/filecoin-project/lotus/blob/master/LOTUS_RELEASE_FLOW.md would need to change if we move that file.

It looks like the contents of the makefile was deleted unintentionally here: cbb76cf#diff-76ed074a9305c04054cdebb9e9aad2d818052b07091de1f20cad0bbac34ffb52, which is why the checks are failing. I will push a change that restores the contents.

I actually intentionally deleted the makefile contents so that there was a very clear error message if anyone does make *. Let me know if you disagree with the approach. If we go with it, I guess I'll need to also remove some of the checks in this branch. I'll write out a list of the other things would need to do.

2024-08-12: Discussed verbally in Zoom that deleting the makefile contents here makes sense. Next steps:

1. Do some additional manual testing, and potentially make this error out/ make it even more verbose to ensure that people see the message
2. Write suggestions on how people should now get the latest tags for node and miner
3. Ask someone that is running scripts building their binary from the releases branch, and get a 👍 that they see the error, and that the new way of getting the latest tags works for them.

I have taken a stab at this with fe42667

Write suggestions on how people should now get the latest tags for node and miner

I did this in #12322 . See https://github.com/filecoin-project/lotus/pull/12322/files#diff-fb3c9ffe7e0886ba95ce77f3809358fd6aa0ca3994f1bd45195d4ce178d68ca4R157

Looks good to me! Just one additional suggestion on making it exit with a non-zero status code.
