Improving email documentation

With an nf-core created pipeline (via nf-core create), there is an email feature, relying on the host system having sendmail setup. Currently, the nf-core documentation seems to suggest that you can simply provide your email as a parameter (--email your.email@domain.com), and it should work out of the box. The nextflow documentation as shown here clarifies the setup requirements for this to work, but nf-core does not. The tips and tricks section of the nf-core documentation mention the email feature as:

Specify --email your@email.com to receive emails when your pipeline completes

I believe this could be changed to something like:

Specify --email your@email.com to receive emails when your pipeline completes. Note that this requires the sendmail linux service to be setup in your environment.

Start with the tips and tricks section of the nf-core documentation and compare its email guidance with the linked Nextflow mail documentation. Update the email note to explain that the host environment must have the sendmail service configured, then verify the wording no longer implies that email works out of the box.
