New module: gtdbtk/gtdbtoncbimajorityvote

Adds a new module: gtdbtk/gtdbtoncbimajorityvote

This requires a couple of changes to the gtdbtk/classifywf module:

• The new module takes as input the files from classifywf, and requires that the structure be as-is. So I've removed the code that re-arranges and tidies up the classifywf outputs
• I've added a new output that outputs everything from gtdbtk/classifywf
• Harshill alignment ☺️
• Bump version to 2.4.1

For the new module, one of the inputs is the prefix used in the gtdbtk/classifywf run - I'm currently just inferring this from the input files. But it could be an explicit input if anyone thinks that's better

Note: It would be good to move the mockup database to somewhere in the nf-core test data sphere, as the download speed is in the range of a handful of kbps.

PR checklist

Closes #XXX

• This comment contains a description of changes (with reason).
• If you've fixed a bug or added code that should be tested, add tests!
• If you've added a new tool - have you followed the module conventions in the contribution docs
• If necessary, include test data in your PR.
• Remove all TODO statements.
• Emit the versions.yml file.
• Follow the naming conventions.
• Follow the parameters requirements.
• Follow the input/output options guidelines.
• Add a resource label
• Use BioConda and BioContainers if possible to fulfil software requirements.
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • For modules:
    • nf-core modules test <MODULE> --profile docker
    • nf-core modules test <MODULE> --profile singularity
    • nf-core modules test <MODULE> --profile conda
  • For subworkflows:
    • nf-core subworkflows test <SUBWORKFLOW> --profile docker
    • nf-core subworkflows test <SUBWORKFLOW> --profile singularity
    • nf-core subworkflows test <SUBWORKFLOW> --profile conda

@jfy133 Since you added the tests the other day - better to leave the empty file in the classifywf test despite causing a lint failure?
