Adding subset of metagrootdb

[angelphanth]

Please fill in the appropriate checklist below (delete whatever is not relevant). These are the most common things requested when adding a new test dataset.

• Check here that there isn't already a branch containing data that could be used
  • If this is the case, follow the documentation on how to use an existing test dataset
• Fork the nf-core/test-datasets repository to your GitHub account
• Create a new branch on your fork
• Check your proposed test data follows the guidelines
• Add your test dataset
  • If you clone it locally use git clone <url> --branch <branch> --single-branch
• Make a PR on a new branch with a relevant name
• Wait for the PR to be merged
• Use this newly created branch for your tests

This pull request adds detailed documentation to the testdata/metagroot/README.md file, describing how to generate a test HMM dataset for MetagRoot. The new instructions clarify the process for obtaining, preparing, and packaging the test data.

Documentation improvements:

• Added step-by-step instructions for downloading, extracting, concatenating, compressing, scanning, subsetting, and repackaging HMM profile files to create a test dataset, including example shell commands.
• Clarified the difference between the HMM.tar.gz and subset_metagroot.hmm files, and provided references to the original data sources.

Just do the required computations by hand and only provide the final test metagroot_test.hmm.gz file here, as in the other parallel folders (e.g., nmpfams, pfam, etc) :D

The deal is, you need to keep 1-2 matching HMMs from the mother file (which I see you already did with your scripts), so just push that one file :D

Thank you! I changed the file in the commit d1cbfac

Approved, but please rename to metagroot_test.hmm.gz before merging (instead of metagrootdb_test.hmm.gz (nitpicking). And have fun with testing the subworkflow :D
