Do not display omnibus and CNG in table of fixes

What does this MR do and why?

Omnibus and CNG security fixes are often dependency updates, based on an external CVE. Historically they have not been included in the Table of Fixes in the blog post.

This MR updates the table to skip listing issues in those projects.

Testing

I ran the release:patch_blog_post rake task with a dry run locally. While I cannot post the content here since it's security info, I can say that it did not include any Omnibus updates in the table. Here's a heavily modified version of the output:

Today we are releasing versions 16.5.1, 16.4.2, 16.3.6 for GitLab Community Edition (CE) and Enterprise Edition (EE).

These versions contain important security fixes, and we strongly recommend that all GitLab installations be upgraded to
one of these versions immediately. GitLab.com is already running the patched version.

GitLab releases patches for vulnerabilities in dedicated security releases. There are two types of security releases:
a monthly, scheduled security release, released a week after the feature release (which deploys on the 3rd Thursday of each month),
and ad-hoc security releases for critical vulnerabilities. For more information, you can visit our [security FAQ](https://about.gitlab.com/security/faq/).
You can see all of our regular and security release blog posts [here](/releases/categories/releases/).
In addition, the issues detailing each vulnerability are made public on our
[issue tracker](https://gitlab.com/gitlab-org/gitlab/-/issues/?sort=created_date&state=closed&label_name%5B%5D=bug%3A%3Avulnerability&confidential=no&first_page_size=100)
30 days after the release in which they were patched.

We are dedicated to ensuring all aspects of GitLab that are exposed to customers or that host customer data are held to
the highest security standards. As part of maintaining good security hygiene, it is highly recommended that all customers
upgrade to the latest security release for their supported version. You can read more
[best practices in securing your GitLab instance](/blog/2020/05/20/gitlab-instance-security-best-practices/) in our blog post.

### Recommended Action

We **strongly recommend** that all installations running a version affected by the issues described below are **upgraded to the latest version as soon as possible**.

When no specific deployment type (omnibus, source code, helm chart, etc.) of a product is mentioned, this means all types are affected.

| Title | Severity |
| ----- | -------- |
| [Fix 1](#fix-1) | Low |
