Avoid pattern creation with some basic gradients

Some gradients are represented as patterns in PDF.js, because they
mustn't be affected by the current transform. But in most of the cases,
the gradient is attached to the origin and the current transform is very
basic (dilatation + orthogonal + translation). In those cases, we can
avoid creating the pattern because the gradient is transformed into
another gradient when the inverse transform is applied.

• src/display/pattern_helper.js

Upgrade @types/node to version 25.0.1

This is a major version bump, but the patch at
https://github.com/DefinitelyTyped/DefinitelyTyped/pull/73924
doesn't indicate any breaking changes that should impact us as it mainly
includes support for Node.js 25.

Run the CI tests in Node.js version 25 too

Node.js version 25 is the current (non-LTS) release, see
