CI test to check download is valid

[ewels]

It would be great to have a CI check to confirm that the new download URL is valid and the sha is correct.

• Check out code before and after proposed merge, parse both JSON trees and find any download URLs / shas that are new or changed
• Try to download them and check the sha

Excellent point. It should also try to use it using this command:

export NXF_PLUGINS_TEST_REPOSITORY=<Plugins JSON URL>
nextflow run hello -plugins declared-plugin@declared-version

Where the JSON URL is the public URL (not local file) of the modified JSON on the PR?

So for #17 it would be this?

export NXF_PLUGINS_TEST_REPOSITORY=https://raw.githubusercontent.com/nvnieuwk/plugins/a0fac2692cf4aef29158ccf3cbadd92c3e2cf463/plugins.json
nextflow run hello -plugins nf-validation@0.2.1
