Update main.nf

[amizeranschi]

Should fix nf-core/funcscan#426

[mahesh-panchal]

This particular change is fine, but please get the tests to work by updating the test snapshots.

nf-core modules test rgi/main --profile <docker/singularity/conda> --update

I updated the snapshot and tests are succeeding locally. ✔️

Why they don't here on GHA: because the untar module (as part of the main.nf.test file) uses ubuntu version 22.04. A previous module version used 20.04 with which all tests succeeded back then and still do now if I change the version back to 20.04 locally. This problem was reported and discussed already in June (see Slack convo here), but not fixed yet, apparently.
Would you @mahesh-panchal be fine with merging this PR incl. failing tests when I assure that tests are fine locally? I attached screenshots in the Slack convo. This PR does not interfere with any of this anyway, it just wants to fix a typo in a variable 😬

@maxulysse What's the plan on implementing this unified container?

is quay.io/nf-core/coreutils_grep_gzip_lbzip2_pruned:10736d98b4d693d8 working as expecting (ie containing the missing lib)?
