Back-merge the 4.0.3 security patch into dev

[mashehu]

Forward-ports the merged master security patch into dev so the fix is a shared ancestor and the coming removal of the momentarily ignored lint tests (coming with nf-core/tools 4.1.0) propagates cleanly.

YAML linting is failing

To keep the code consistent with lots of contributors, we run automated code consistency checks.
To fix this CI test, please run:

• Install yaml-lint
  • Install npm then install yaml-lint (npm install -g yaml-lint)
• Fix the markdown errors
  • Run the test locally: yamllint $(find . -type f -name "*.yml" -o -name "*.yaml")
  • Fix any reported errors in your YAML files

Once you push these changes the test should pass, and you can hide this comment 👍

We highly recommend setting up yaml-lint in your code editor so that this formatting is done automatically on save. Ask about it on Slack for help!

Thanks again for your contribution!

Markdown linting is failing

To keep the code consistent with lots of contributors, we run automated code consistency checks.
To fix this CI test, please run:

• Install markdownlint-cli
  • On Mac: brew install markdownlint-cli
  • Everything else: Install npm then install markdownlint-cli (npm install -g markdownlint-cli)
• Fix the markdown errors
  • Automatically: markdownlint . --config .github/markdownlint.yml --fix
  • Manually resolve anything left from markdownlint . --config .github/markdownlint.yml

Once you push these changes the test should pass, and you can hide this comment 👍
