Add option to generate random string similar to #[now], or #[short-random]

Is your feature request related to a problem? Please describe.
As a test engineer I need an option to generate random strings with only a-Z chars

Describe the solution you'd like
New case in Scenario var - com/cucumber/utils/context/vars/ScenarioVars.java - for string-random
case "string-random":
return RandomStringUtils.random(new Random().nextInt(50), true, false);

I believe #[uid] is not applicable here, since it also contains numbers.

However, instead of implementing new dedicated scenario variables, you may wanna use a less coarsened solution, such as the SpEL feature (available since version 5.38):

  * var s="#{T(org.apache.commons.lang3.RandomStringUtils).random(new java.util.Random().nextInt(50), true, false)}"

will generate:

var s = oKGiXPmTNkUgnxgVUzoaPlrRYZYZLqDARDtY

Or,

* var s="#{T(your.project.package.Utils).randomString()}"

where randomString() is a public & static method defined inside one of your utility classes.

Does that suffice ?

Otherwise, you may submit a pull request if interested in adding this special variable. Though in this special case, the random String boundaries are somewhat hard to pre-define. You may want 50, others may want 100.
