Fix test profile to use GitHub URLs for test data

Updated test samplesheet and config to reference GitHub raw URLs
instead of relative paths. This ensures test data is accessible
when running the pipeline on Seqera Platform.

Changes:
- Updated samplesheet.csv to use full GitHub raw URLs for FASTQ files
- Updated nextflow.config test profile to use GitHub URLs for reference FASTAs
- All test data now accessible via https://raw.githubusercontent.com/
