False positive for Jinja variables regex (test provided + failing CI output)

[myii]

Describe the bug

Encountered a false positive for the Jinja variables check, based on this block:

  file.blockreplace:
    - ...
    - content: |
           DKIM_DOMAIN = ${lc:${domain:$h_from:}}
           DKIM_KEY_FILE = /etc/exim4/dkim/{{ pillar['dkim_private_key'] }}
           DKIM_PRIVATE_KEY = ${if exists{DKIM_KEY_FILE}{DKIM_KEY_FILE}{0}}
           DKIM_SELECTOR = {{ pillar['dkim_selector'] }}

With the error being:

[206] Jinja variables should have spaces before and after: '{{ var_name }}'
.../init.sls:71
           DKIM_DOMAIN = ${lc:${domain:$h_from:}}

To Reproduce

I've provided a failing test here:

• myii@df975f1

As I've mentioned there, it fails within quotes as well:

    - content: 'DKIM_DOMAIN = ${lc:${domain:$h_from:}}'

Here's the failure in GitHub Actions based on that commit:

• https://github.com/myii/salt-lint/actions/runs/2441054851

Note, there's also another commit there, which adjusts the CI so that the yamllint error is resolved and the CI doesn't fail fast (so that all instance failures can be seen):

• myii@3b5c7a3

Let me know if you'd like that in a PR here.

Expected behavior

The regex shouldn't catch this as a failure.
