fix sphinx-init --fail-on-error trailing backslash

[briantist]

I found that using --fail-on-error with sphinx-init resulted in a broken build.sh due to a missing trailing backslash.

Example:

#!/usr/bin/env bash
set -e
cd /home/runner/work/_temp/docsbuild

# Create collection documentation into temporary directory
rm -rf temp-rst
mkdir -p temp-rst
antsibull-docs collection \
    --fail-on-error
    --use-current \
    --no-use-html-blobs \
    --breadcrumbs \
    --indexes \
    --dest-dir temp-rst \
    lowlydba.sqlserver

# Copy collection documentation into source directory
rsync -cprv --delete-after temp-rst/collections/ rst/collections/

# Build Sphinx site
sphinx-build -M html rst build -c . -W --keep-going

Code looks good, but can you please add a changelog fragment? Thanks :)

I was thinking of waiting for a run of the test docsite build (for ansible/ansible#77362). I hope that can happen tomorrow...

Sounds good to me, not a huge rush, a comment here or a ping on IRC when it's released would be great if you remember 🙏

@briantist I just released 0.42.1 with this fix.
