`:1234:` is converted to emoji when found w/in an IPv6 address

[jasikpark]

Describe the bug

npmx:

---

GitHub:

---

https://npmx.dev/package/ipaddr.js has example IPv6 addresses in code blocks that include the string :1234:, which npmx's slack emoji turns into 🔢. This shouldn't happen.

Additional context

• https://npmx.dev/package/ipaddr.js

I think the fix is to not convert to emojis inside a code block
