Jekyll 3.5 needed for concat to work

Github Pages used Jekyll 3.4.5 :(

Using array push as workaround.

{% assign tags_tut =  site.tutorials | map: 'tags' | join: ','  | split: ',' | uniq %}
{% assign tags_ref =  site.references | map: 'tags' | join: ','  | split: ',' | uniq %}

{% assign tags = site.emptyArray %}

{% for tag in tags_tut %}
  {% assign tags = tags | push: tag %}
{% endfor %}
{% for tag in tags_ref %}
  {% assign tags = tags | push: tag %}
{% endfor %}

{% assign tags = tags | uniq %}
