Update README.md

[CajNoble]

Noticed that the paragraph following the code the bloc seemed to inherit a plain text format. This appears to have been removed by removing the indentation.

What does this PR do?

This PR should make the bloc of text following a code block its own paragraph. It appears to have inherited a plain text format due to the indentation.

Motivation

The formatting looked out of line with our normal documentation. This change should re-align to our formatting expectations.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• PR title must be written as a CHANGELOG entry (see why)
• Files changes must correspond to the primary purpose of the PR as described in the title (small unrelated changes should have their own PR)
• PR must have changelog/ and integration/ labels attached
• If the PR doesn't need to be tested during QA, please add a qa/skip-qa label.
