chore(config): migrate renovate config

[renovate]

The Renovate config in this repository needs migrating. Typically this is because one or more configuration options you are using have been renamed.

You don't need to merge this PR right away, because Renovate will continue to migrate these fields internally each time it runs. But later some of these fields may be fully deprecated and the migrations removed. So it's a good idea to merge this migration PR soon.

PLEASE NOTE: JSON5 config file migrated! All comments & trailing commas were removed.

🔕 Ignore: Close this PR and you won't be reminded about config migration again, but one day your current config may no longer be valid.

❓ Got questions? Does something look wrong to you? Please don't hesitate to request help here.

Hi @renovate[bot],

It looks like this pull-request is has been made against the nf-core/tools main branch.
The main branch on nf-core repositories should always contain code from the latest release.
Because of this, PRs to main are only allowed if they come from the nf-core/tools dev branch.

You do not need to close this PR, you can change the target branch to dev by clicking the "Edit" button at the top of this page.
Note that even after this, the test will continue to show as failing until you push a new commit.

Thanks again for your contribution!
