Pages Files Documentation Update

### Existing documentation URL(s)

https://developers.cloudflare.com/pages/platform/limits/#files:~:text=Pages%20uploads%20each,Pages%20project%20settings.

https://developers.cloudflare.com/changelog/2026-01-23-pages-file-limit-increase/

### What changes are you suggesting?

The following URL states: “Paid plans can now have up to 100,000 files per Pages site, increased from the previous limit of 20,000 files”:
https://developers.cloudflare.com/pages/platform/limits/#files:~:text=Pages%20uploads%20each,Pages%20project%20settings

However, this wording is causing confusion, as “Paid plans” is being interpreted as referring to zone-level plans rather than the Workers Paid Plan. I suggest updating the wording to explicitly say “Workers Paid Plan” to clearly indicate which plan type the limit applies to.

The same clarification should also be made in this changelog entry:
