Card titles do not have the correct possessive form for names ending in "x"

[TenType]

Describe the bug

In the GitHub Stats card, users with names ending in "x" do not have the correct possessive form of their name in their titles.

For example, a user with the name Max is displayed as Max' GitHub Stats instead of Max's GitHub Stats.

Expected behavior

Users with names ending in "x" should have a title with apostrophe-s, not just an apostrophe.

Additional context

Here are the pertinent lines of code that cause this issue:

Why was "x" included in this case? It is common to omit the "s" for names ending in "s", but I don't see how this makes grammatical sense for names ending in "x".

Sorry if this is pedantic, but this caught the corner of my eye when I was using this project.
