Update ANTISMASH to 6.1.1 and enable_conda replacement

[jfy133]

This updates

• ANTISMASH to 6.1.1 (fixing jinja import errors)
• Uses a new method of detecting whether conda is being used or not to correctly set paths for downloading

Note: it's still not ideal as may not work for locally instlaled tool pipeline runs (i.e., without conda/docker/singularity) but we don't really want this in nf-core as it's against reproducibilty

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:
  • PROFILE=docker pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
  • PROFILE=singularity pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
  • PROFILE=conda pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware

Looks like an awesome solution 🥳 (if all tests pass of course)
