DEVDOCS-6658 Normalize line endings to LF (#1212)

# [DEVDOCS-6658]

## What changed?
This change normalizes all text files in the documentation repository to
use LF (`\n`) line endings

To easily review this, get Github to ignore whitespace changes in the
diff by adding `?w=1` to the URL:
https://github.com/bigcommerce/docs/pull/1212/files?w=1

## Why?
- LF is the standard line ending for cross-platform repositories
- Prevents noisy diffs caused by mixed CRLF/LF endings. I have a number
of other updates lined up but ended up with gaint diffs because of the
line-endings, so let's standardise them first

Proof that this is only changing line endings and nothing else:
