Bump factory revision (rebuild against flint 3.4.0)

[d-torrance]

This should fix the current failing builds in the M2 repo, e.g., from https://github.com/Macaulay2/M2/actions/runs/19684168550/job/56385474365?pr=4040:

Why do you bump more than once?

[d-torrance]

I had already bumped to a revision 3 to add tahoe packages a couple weeks ago, but you suggested that I revert those changes. But that bottle had already been uploaded, I guess, so the "pr-pull" step for this PR failed.

[d-torrance]

Ah, I guess brew audit wants the revision to increment by exactly 1. I guess we should delete the old revision 3 bottle. It doesn't look like I have the right permissions. @mahrud - do you? Or is this something we need to bug Mike about?

[mahrud]

This may be only possible using oras.

[d-torrance]

According to the docs there's a delete button for folks with the right permissions.

@mikestillman - do you have the option of deleting the 4.4.1_3 factory bottle on https://github.com/Macaulay2/homebrew-tap/pkgs/container/tap%2Ffactory/versions?filters%5Bversion_type%5D=tagged?

[d-torrance]

I came up with a dumb solution: I bumped the factory revision on the main branch to 3 so that we could bump it to 4 here without brew audit complaining.

@mikestillman - Don't worry about deleting that bottle.
