Description
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:
https://github.com/anuraghazra/github-readme-stats/blob/25a9dabf13dd8891a96be2421b2b0ed98761f504/src/cards/stats-card.js#L257C1-L259C11
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.
