Change instances of violent language to use non-violent alternatives

Step 1: What is changing in this MR?

I am changing instances of the word "trigger" to "engage" in the Support page. The word "trigger" is most commonly used with firearms and other negative definitions. While one could argue that it also has non-violent associations, the alternative "engage" has a less violent connotation in English. Additionally, "engage" holds a similar meaning of immediately initiating something, so the overall meaning remains the same.

We have a precedent of avoiding terms that may have violent connotations, even in cases where the origin is not exactly clear.

Step 2: Ensure that your changes comply with the following, where applicable:

Since this is effectively a find-and-replace for a single string, I don't think anything below applies. If the reviewer would like, I am happy to complete any of the following.
