Pin version of nf-validation and nf-iridanext

[apetkau]

Issue

An upcoming upgrade of the nf-validation plugin from 1.1.3 to 2.0.0 will make breaking changes (nextflow-io/plugins#66). Right now, this pipeline uses the latest version of nf-validation and so will stop functioning when this upgrade occurs.

Solution

1. Pin Nextflow plugin versions
   These should be pinned to specific versions (i.e., change to nf-validation@1.1.3 and nf-iridanext@0.2.0). Pinning nf-iridanext since we might as well pin all plugin versions in this fix.

   fetchdatairidanext/nextflow.config

   Lines 156 to 160 in 603ee7e

   	// Nextflow plugins
   	plugins {
   	id 'nf-validation' // Validation of pipeline parameters and creation of an input channel from a sample sheet
   	id 'nf-iridanext'
   	}

2. Update version
   Update version to indicate a bug fix to 1.0.1:

   fetchdatairidanext/nextflow.config

   Line 201 in 603ee7e

   version = '1.1.0.dev'

3. Update CHANGELOG.md to list the change. https://github.com/phac-nml/fetchdatairidanext/blob/dev/CHANGELOG.md
