[5.1.0] Fix components

grimreaper → credited pdureau → .

Lets use range() function instead of the .. built-in operator because:

• .. is just syntactic sugar for the range() function. So, 1..items|length is the same as range(1, items|length), but without the possibility of adding a step
• .. doesn't' exist in Jinja and Nunjucks, but range() function does.
• Using a function will let us benefit for a check on function parameters we plan to introduce later
