incorrect format of create-params-file

[matbonfanti]

Description of the bug

The command nf-core pipelines create-params-file is intended to generate a YAML-formatted file that can be used as a parameters file for Nextflow execution (-params-file argument). However, the generated file incorrectly uses the format "name = value" instead of the correct YAML syntax "name: value". This causes issues when trying to use the file as a valid input for Nextflow.

Command used and terminal output

$ nf-core pipelines create-params-file --output ./nf-params.yml nf-core/sarek

Here are the first lines of the nf-params.yml output:

===

## ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
##     nf-core/sarek 3.5.0
## ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
##     This is an example parameter file to pass to the `-params-file` option
##     of nextflow run with the nf-core/sarek pipeline.
##
##     Uncomment lines with a single '#' if you want to pass the parameter to
##     the pipeline.
