templating

[gmanchon]

adds liquid templating

replaces partials substituted constants <PYTHON_VERSION> with variables {{ PYTHON_VERSION }}

replaces partials delimiter-structured blocks :

$MAC_START
  ...
$MAC_END
$WINDOWS_START
  ...
$WINDOWS_END
$LINUX_START
  ...
$LINUX_END

with conditionals :

{% if os == "macos" %}
  ...
{% elsif os == "windows" %}
  ...
{% elsif os == "linux" %}
  ...
{% endif %}

no diffs in generated localised build files appart from blank lines

specific repo diffs

replicates lewagon/data-setup#361

Hello @ajdubovoy 👋

I updated the build gha to support liquid templating in order to simplify the edition of the _partials instructions

The main differences in the code structure are :

• the variables available to all partials, as {{ RUBY_SETUP_VERSION }}, are stored in constants/constants.yml
• the formulas are now stored in builds in yaml format, for example builds/LINUX.yml
• it will soon be possible to parametrise a partial in order to adapt its content to the setup it is called from

No changes are made to the existing instructions

The code is a bit overkill for this repo since the setup only uses local partials, but this way the gha is coherent with the ones of the DS, DA and DE setups

Thanks for the update!
