[kots]: correctly escape params in installation configmap

[mrsimonemms]

Description

Values in the gitpod-installation config map are incorrectly escaped. If a ' was introduced into the release notes, this would cause the YAML to become invalid.

The escaping of these values has been amended to be applied correctly, and added the use of the | quote pipe (which works identically to Helm).

How to test

Run the command:

replicated release create \
  --lint \
  --ensure-channel \
  --yaml-dir ./install/kots \
  --promote ${REPLICATED_DEV_CHANNEL} \
  --release-notes "some release's \" note" \
  --version="$(date +%s)"

This will push a new release to your dev channel. This will allow you to run "check for updates" in the KOTS dashboard and then you'll see beautifully escaped YAML when you "view files"
