Example of bowtie2+subread

[Hadolint](https://github.com/hadolint/hadolint) (used by nf-core/tools) recommends to add

- `--no-install-recommends`
- specific version, which I took from [debian.org/distrib/packages](https://www.debian.org/distrib/packages)

Then the solution for ARM packages pinned looks like:

```bash
# ARM specific Dockerfile
FROM debian:13

WORKDIR /app

RUN apt-get update \
&& apt-get -y install --no-install-recommends \
bowtie2=2.5.4-1+b2 \
curl=8.14.1-2+deb13u2 \
samtools=1.21-1 \
subread=2.0.8+dfsg-1 \
&& rm -rf /var/lib/apt/lists/*

COPY scripts/ ./scripts/
```

Hadolint version: `Haskell Dockerfile Linter 2.14.0`

The issue provides an ARM-specific Dockerfile snippet that installs bowtie2, curl, samtools, and subread, then copies scripts/ into the image, but it names no repository file to change. Start by locating the relevant Dockerfile or training example and clarify whether this snippet should be added as documentation or an executable example; done means the intended example is present and its package pins are validated.
