Add and fix ECLint in pipeline

[drpatelh]

• Add EditorConfig linting similar to Editorconfig rnaseq#627
• Simplified default comments everywhere because ECLint was left-aligning them and they looked terrible.
• Changed comment header format in all of the template files too

This took way longer than I wanted it to but the code base should be even nicer and more consistent going forward!!

All of the tests seem to be happy so I hope I haven't broke something somewhere with all of this re-formatting! Bit late in the day now given we are releasing soon. Oh well 🤷🏽

Some minor comments but otherwise awesome as always 👍

Should we open an issue to update the comments when using nf-core modules create?
Although, this will also require to update/reinstall all the functions.nf on modules/nf-core/software 😅

[drpatelh]

Yes, please 👀 Will need to look for these comments in the entire module repo. Copying the functions.nf shouldn't be much work. Think I have a script for that 🤔 Problem is that they get left-aligned with the new EClint which makes everything untidy so better to just replace them once and for all everywhere I think.
