[FEATURE] Promote ng version

[n-rodriguez]

It could be nice to promote the ng version of this formula.

Sounds good. We'd need to go through the same steps as when we promoted other ng formulas.

saltstack-formulas/template-formula#21 has links to previous conversions.

+1 for promoting ng and doing deprecation steps

[myii]

To be more helpful, it's the section:

• Investigate how the semantic-release (and/or the TOFS pattern?) can be used to mitigate the use of formula:ng states
  • ...
  • Most complete conversion method (in stages) done for the php-formula:
    • fix: warn formula users ng states will be promoted in v1.0.0 php-formula#185
    • fix: update deprecation version number in semantic-release run php-formula#187
    • feat(ng): promote NG formula php-formula#183

Those PRs are in the order of things to be done. I'm not sure but maybe one of them had multiple steps involved.
