TEMPLATE - add trainling slash for pipelines_testdata_base_path

[maxulysse]

from @vagkaratzas

Would it be too much pain to put a slash at the end of pipelines_testdata_base_path in tests/nextflow.config, in the next template update? Currently it's different to the modules_testdata_base_path above. Would be nice to have uniformity in tests throughout conf/ tests/ and modules-subworkflows tests. I've left a relevant though-comment on this PR: https://github.com/nf-core/methylseq/pull/558#discussion_r2253615940

good question, maybe we should indeed

hmm, not sure it's worth the template merge pain to be honest. Maybe we can bookmark the change and do it in the future, together with other changes that we may need to make then?
