Adapt Dockerfile for arm64 and some requirements changes

[alneberg]

1. Download and compile minimap2 for arm64 instead of installing via micromamba
2. Change minimap2 version from 2.20 to 2.26
3. Move requirements to requirements.txt instead of environment.yml and inside setup.py
4. Use base environment inside docker instead of named anglerfish environment
5. Upgraded biopython from 1.79 to 1.83
6. Upgraded numpy from 1.22.0 to 1.26.3
7. Upgraded pyyaml from 6.0 to 6.0.1

Not convinced these are the best options, so open for feedback!
