Revert CheckM2 database download workaround and update modules

[dialvarezs]

This PR updates CheckM2 modules to newer versions using topics.
And also reverts the workaround introduced in #966 since it's no longer necessary, because the module was patched to set the UA in nf-core/modules#9744

But, more importantly, the workaround introduced a bug that we didn't notice: the CheckM2 database channel was being consumed after one process, so CheckM2 (and so GTDB-TK that depends on the Bin QC channel) was effectively executing only for one bin/unbin set.

I detected this recently looking at full tests runs on Seqera Cloud:

You see only 1 CheckM2 and 0 GTDB-Tk jobs because CheckM2 processed an "unbin" set, so it didn't make the cut for the qc threshold.
