Icon change: Nextflow

[ewels]

The logo for Nextflow has updated.

Current logo in the repo is here, which should be removed and replaced with the following (source):

<svg width="251" height="251" viewBox="0 0 251 251" fill="none" xmlns="http://www.w3.org/2000/svg">

Hopefully it's pretty well optimised already, it's a simple shape and there are very few SVG points 🙏🏻 Happy to put in a PR if that'd help, but following the guidelines.

Thanks in advance!
