[vite-plugin-content] Upgrade deps for security

[pcorpet]

Versions

• originjs: v1.0.5
• node: v23.7.0

Reproduction

The current version of the package has 1 vulnerable dependency:

• xlsx (currently ^0.20.0): GHSA-5pgg-2g8v-p4x9

The fix should be to bump xlsx to 0.20.2 and do a release like you did to fix #196

Thanks!
