QE review:
QE is not required for this PR. This PR modularizes Network Observability Operator release notes for 1.3.0 only. There are no content changes.

Additional information:

• For 1.8.0, per new guidance, there is an exception for xrefs in release notes modules. xrefs have been left as they are. There is a separate Jira to update xrefs in all newly created Network Observability Operator release note modules.
• The Network Observability Operator release notes are being modularized through a series of PRs. This means that things will get cleaned up and consolidated along the way.
• Some of these PRs may contain updates to previously merged content for the purpose of consistency.
• The network-observability-release-notes.adoc file will dwindle with each PR while the network-observability-operator-release-notes-archive.adoc file will grow.
  In as many cases as possible, such as:
  [id="network-observability-channel-removal-1.4_{context}"]
  == Channel removal
  existing ID in network-observability-release-notes.adoc has been used in the new module.
• Since not all content applies to every OCP branch, it is possible there will be cherry-pick failures. This will likely apply to release notes since it has been 1 assembly file and not all content is applicable to all OCP branches.
• I will manually verify content on each breach, and create manual cherry-picks accordingly.
