Update rand to 0.9

[JonathanWoollett-Light]

Closes #318

[hanyuone]

Would upgrading rand to v0.9 also involve upgrading getrandom to v0.3? Relevant information in the upgrade guide for rand here.

[ramosbugs]

see #306

[CosminPerRam]

Although this isn't merged, consider rand 0.10.

[hanyuone]

From rand 0.10 onwards, getrandom 0.4 is used, which no longer requires any extra rustflags, thus not leading to a breaking change for a major version (the issue seen in #306).

@ramosbugs would a PR that bumps the rand version to 0.10 be accepted?

[CosminPerRam]

@hanyuone probably not (unless with a new major), the MSRV for 0.10 is 1.85.0, whereas we are on 1.65.0

[hanyuone]

@CosminPerRam I see - although could #306 be merged now, since getrandom v0.3.4 uses the wasm_js backend by default, thus removing the need for setting rustflags? See the changelog for getrandom here.

Hi ! I would love to see this merged. I currently have three different versions of rand built into sqlpage !

I think I'm not the only one who wouldn't mind a new major version being released.
