dependency: (deps): bump pypdfium2 from 4.30.0 to 4.30.1 in /backend

[dependabot]

Bumps pypdfium2 from 4.30.0 to 4.30.1.

Release notes

Sourced from pypdfium2's releases.

4.30.1

Changes (Release 4.30.1)

Summary (pypdfium2)

• PdfPage.get_objects(): Don't register pageobjects as children, because they don't need to be closed by the caller when part of a page. This avoids excessive caching of weakrefs that are not cleaned up with the object they refer to.
• Fixed another dotted filepath blunder in the extract-images CLI. (The PdfImage.extract() API is not affected this time.)
• Adapted setup code to bdist_wheel relocation (moved from wheel to setuptools).
• Fixed installation with reference bindings (PDFIUM_BINDINGS=reference) by actually including them in the sdist and adding a missing mkdir call. (In older versions, this can be worked around by cloning the repository and creating the missing directory manually before installation.)
• Fixed sourcebuild on windows by syncing patches with pdfium-binaries.
• Updated test expectations: due to changes in pdfium, some numbers are now slightly different.
• Fixed conda packaging: It is now required to explicitly specify -c defaults with --override-channels, presumably due to an upstream change.
• Autorelease: Swapped default condition for minor/patch update, as pypdfium2 changes are likely more API-significant than pdfium updates. Added ability for manual override.
• Bumped workflows to Python 3.12.
• Updated docs on licensing.
• This is expected to be the last release of the v4 series.
