[bug]: Outdated typescript dependency

[ChristopheCVB]

What version of @strapi/sdk-plugin are you using?

• PNPM: 10.19.0
• Node: 22.21.0
• @strapi/plugin-sdk: 5.3.2
• Project typescript: 5.9.3

What's Wrong?

Due to the fact that this package uses an old version of typescript, types are outdated and produces types error at build time.

To Reproduce

admin/src/components/Hello.tsx

      // eslint-disable-next-line @typescript-eslint/ban-ts-comment
      // @ts-ignore - @strapi/sdk-plugin uses an old typescript version
      const dynamiczoneHeaderTitle = dynamiczoneHeader.querySelector<HTMLSpanElement>('span:first-child')?.textContent.trim()
      //                                                                                                   ^^^^^^^^^^^ Object is possibly null

Expected Behaviour

Build should pass

Another thing to mention is that the typescript version used (5.4.4) is not compatiple with dependency versions pulled in by strapi core.

Through @types/strapi it pulls in typedoc at version 0.25.x which only advertises support up to typescript 5.3.x.
This leads to errors installing dependencies with strict peer versioning enabled.
