Bump jszip and mammoth in /backend

[dependabot]

Bumps jszip and mammoth. These dependencies needed to be updated together.
Updates jszip from 2.5.0 to 3.10.1

Changelog

Sourced from jszip's changelog.

v3.10.1 2022-08-02

• Add sponsorship files.
  • If you appreciate the time spent maintaining JSZip then I would really appreciate your sponsorship.
• Consolidate metadata types and expose OnUpdateCallback #851 and #852
• use const instead var in example from README.markdown #828
• Switch manual download link to HTTPS #839

Internals:

• Replace jshint with eslint #842
• Add performance tests #834

v3.10.0 2022-05-20

• Change setimmediate dependency to more efficient one. Fixes Stuk/jszip#617 (see #829)
• Update types of currentFile metadata to include null (see #826)

v3.9.1 2022-04-06

• Fix recursive definition of InputFileFormat introduced in 3.9.0.

v3.9.0 2022-04-04

• Update types JSZip#loadAsync to accept a promise for data, and remove arguments from new JSZip() (see #752)
• Update types for compressionOptions to JSZipFileOptions and JSZipGeneratorOptions (see #722)
• Add types for generateInternalStream (see #774)

v3.8.0 2022-03-30

• Santize filenames when files are loaded with loadAsync, to avoid "zip slip" attacks. The original filename is available on each zip entry as unsafeOriginalName. See the documentation. Many thanks to McCaulay Hudson for reporting.

v3.7.1 2021-08-05

• Fix build of dist files.
  • Note: this version ensures the changes from 3.7.0 are actually included in the dist files. Thanks to Evan W for reporting.

v3.7.0 2021-07-23

• Fix: Use a null prototype object for this.files (see #766)
  • This change might break existing code if it uses prototype methods on the .files property of a zip object, for example zip.files.toString(). This approach is taken to prevent files in the zip overriding object methods that would exist on a normal object.

v3.6.0 2021-02-09

• Fix: redirect main to dist on browsers (see #742)
• Fix duplicate require DataLengthProbe, utils (see #734)
• Fix small error in read_zip.md (see #703)

v3.5.0 2020-05-31

Updates mammoth from 1.4.9 to 1.5.1

Changelog

Sourced from mammoth's changelog.

1.5.1

• Fix: npm 7 changed the behaviour of prepublish, causing the browser build not to be updated before publishing to npm. We now use prepare instead of prepublish, which has the same behaviour that prepublish previously had.

1.5.0

• Only use the alt text of image elements as a fallback. If an alt attribute is returned from the function passed to mammoth.images.imgElement, that value will now be preferred to the alt text of the image element.

1.4.21

• Ignore w:u elements when w:val is missing.

1.4.20

• Emit warning instead of throwing exception when image file cannot be found for a:blip elements.

1.4.19

• Add TypeScript declarations.

1.4.18

• When extracting raw text, convert tab elements to tab characters.

• Handle internal hyperlinks created with complex fields.

• Update JSZip to 3.2.0. This addresses CVE-2021-23413 in JSZip.

1.4.17

• Handle w:num with invalid w:abstractNumId.
• Update underscore to 1.13.1.

1.4.16

• Convert symbols in supported fonts to corresponding Unicode characters.

1.4.15

• Support numbering defined by paragraph style.

1.4.14

• Add style mapping for all caps.
