Certain tags in subworkflows aren't parsed correctly while linting

Description of the bug

For UTILS_NFVALIDATION_PLUGIN, I had to add the following tags to get the nf-core linting to get it to pass:

    tag "plugin/nf-validation"
    tag "'plugin/nf-validation'"

If I didn't include the double quoted tag it didn't like it.

Command used and terminal output

nf-core --verbose subworkflows lint utils_nfvalidation_plugin

│ utils_nfvalidation_plugin  │ subworkflows/nf-core/utils_nfvalidation_plugin/tests/main.nf.test │ Tags do not adhere to guidelines. Tags missing in main.nf.test:          │
│                            │                                                                   │ ["'plugin/nf-validation'"]

For one of my local workflows, I had to add a single quote at the end, inside double quote as in "gt/gff3validator'" to pass the lint.
