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:

• https://github.com/myii/salt-lint/commit/df975f167341b3a24d3d3fce6c124f9b03dcdb09

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):

• https://github.com/myii/salt-lint/commit/3b5c7a3fed5f569a656b0852f99d275a766350e3

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

Expected behavior

The regex shouldn't catch this as a failure.
