Add parameter to get_the_term_list() to allow templating

[davidjlaietta]

Similar to #27238 the parameter $term_template is suggested to allow for user created formatting for get_the_term_list(), as opposed to the previous standard of simply linking to each list in the term.

The reasoning for the change is that general linking is not always the desired action for displaying term lists. The method for inclusion is similar to [30209].

inclusion of $term_template argument

Would like to see unit tests for this. Also, if we're going to add support here, we should also add it to functions that call get_the_term_list() - namely, get_the_tag_list().

A proposal was made to display categories and tags without links in the Gutenberg Post Terms block.

The Post Terms block uses get_the_term_list() function internally, so I think this is related to this ticket.

There already are multiple functions for displaying the terms without links, please document what the benefit of this change would be.
