[Small Typo] Display Issue with W\^X on Mitigations Page

[pufanyi]

Hello,

Thanks so much for the great textbook!

I noticed a small display issue on the mitigations page of the CS161 textbook. The text W\^X does not render correctly in the browser; it appears to be a typo or formatting error.

textbook/memory-safety/mitigations.md

Line 41 in 1e30910

This defense has several names in practice, including W\^X (Write XOR Execute), DEP (Data Execution Prevention), and the NX bit (no-execute bit).

Here is how it looks in my browser (link here):

It might be more appropriate to change it to W^X for the correct display.

Thank you!
