docs: Replace incorrect Markdown with a blockquote (#377)

In
https://snakemake.github.io/snakemake-plugin-catalog/plugins/executor/slurm.html#setting-up-a-global-profile,
there is a sentence that isn't formatted correctly:

```
==This is ongoing development. Eventually, you will be able to annotate different file access patterns.==
```

This PR changes that into a blockquote, which looks better:

> This is ongoing development. Eventually, you will be able to annotate
different file access patterns.==
