Update package.json

[redimongo]

Just added react 19, as it shouldn't break, but I haven't yet tested it, maybe someone else can test as I can't work out how to test this change - sorry.

here is a list of issues when I did try and install this.

npm install
npm warn deprecated @npmcli/move-file@1.1.2: This functionality has been moved to @npmcli/fs
npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated stable@0.1.8: Modern JS already guarantees Array#sort() is a stable sort, so this library is deprecated. See the compatibility table on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#browser_compatibility
npm warn deprecated rimraf@2.7.1: Rimraf versions prior to v4 are no longer supported
npm warn deprecated npmlog@6.0.2: This package is no longer supported.
npm warn deprecated har-validator@5.1.5: this library is no longer supported
npm warn deprecated rimraf@3.0.2: Rimraf versions prior to v4 are no longer supported
npm warn deprecated are-we-there-yet@3.0.1: This package is no longer supported.
npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported
npm warn deprecated glob@7.1.7: Glob versions prior to v9 are no longer supported
npm warn deprecated q@1.5.1: You or someone you depend on is using Q, the JavaScript Promise library that gave JavaScript developers strong feelings about promises. They can almost certainly migrate to the native JavaScript promise now. Thank you literally everyone for joining me in this bet against the odds. Be excellent to each other.
npm warn deprecated
npm warn deprecated (For a CapTP with native promises, see @endo/eventual-send and @endo/captp)
npm warn deprecated npmlog@5.0.1: This package is no longer supported.
npm warn deprecated are-we-there-yet@2.0.0: This package is no longer supported.
npm warn deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm warn deprecated gauge@4.0.4: This package is no longer supported.
npm warn deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm warn deprecated gauge@3.0.2: This package is no longer supported.
npm warn deprecated svgo@1.3.2: This SVGO version is no longer supported. Upgrade to v2.x.x.
npm warn deprecated node-sass@7.0.3: Node Sass is no longer supported. Please use `sass` or `sass-embedded` instead.

I will folk this project and re look at the full code, but it will take time.
