Minor changes: Fix formatting in the controls document

[pratiklotia]

When the controls doc was imported to csv, we overlooked that some controls are split on two lines instead of one. For example, in the document here: https://raw.githubusercontent.com/cloud-native-security-controls/controls-catalog/main/controls/controls_catalog_v1.0.csv, between ID 10 and 11, the NIST mapping is actually on a different line. Thankfully, this is not affecting the rendering of the doc but creates confusion when we are making changes to the raw document. There are quite a few such cases where the controls are split on separate lines. It can be easily seen in the PR https://github.com/cloud-native-security-controls/controls-catalog/pull/18/files --- line 11, 18, 33, etc.

This is a good first issue for any new contributors in the team.

@pratiklotia did you have a suggestion; like don't use newlines in any field? I noticed this but since it rendered fine using double quotes I left it as is
