Arm profile platform should be linux/arm64

[birnbera]

Description of the bug

In #1425 config was added for ARM compatible docker images. However, in the corresponding arm profile, it still sets the docker platform as linux/amd64:

rnaseq/nextflow.config

Line 193 in b96a753

docker.runOptions = '-u $(id -u):$(id -g) --platform=linux/amd64'

Since arm.config references images that are ARM-only, when you try to run with the arm profile, you get errors from the docker engine, like:

docker: image with reference community.wave.seqera.io/library/grep_sed_tar:4b2523b1c76a5494 was found but does not match the specified platform: wanted linux/amd64, actual: linux/arm64.

Getting rid of the extra docker.runOptions from the arm profile fixes the issue.

I'd be happy to make this simple PR. If I should, would it be considered a patch PR to master since it's technically a bug in the released version or would I make a PR against dev? Also, for patches, the instructions to bump the version seem inadequate given the large number of places where the version is referenced, such nf-test snap files and the CHANGELOG.
