[9.x] Allow use of brick/math 0.9.3 to enable compatibility with Nova 3

[colincameron]

9.48 broke compatibility with Nova 3.32 due to the introduction of brick/math in #45602 - trying to update to 9.48 gives the following problem:

Problem 1
- laravel/framework v9.48.0 requires brick/math ^0.10.2 -> satisfiable by brick/math[0.10.2].
- Conclusion: don't install brick/math 0.10.2 (conflict analysis result)
- Root composer.json requires laravel/nova * -> satisfiable by laravel/nova[3.32.0].
- Root composer.json requires laravel/framework ^9.48 -> satisfiable by laravel/framework[v9.48.0, 9.x-dev].
- laravel/nova 3.32.0 requires brick/money ^0.5.0 -> satisfiable by brick/money[0.5.0, 0.5.1, 0.5.2, 0.5.3].
- brick/money[0.5.0, ..., 0.5.3] require brick/math ~0.7.3 || ~0.8.0 || ~0.9.0 -> satisfiable by brick/math[0.7.3, ..., 0.9.3].
- You can only install one version of a package, so only one of these can be installed: brick/math[0.7.3, ..., v0.11.x-dev].
- laravel/framework 9.x-dev requires brick/math ^0.10.2|^0.11 -> satisfiable by brick/math[0.10.2, 0.11.0, v0.11.x-dev].
- Conclusion: don't install brick/math 0.11.0 (conflict analysis result)

The requirement for brick/math was extended to allow 0.11 in #45762. This PR relaxes the requirement further to allow 0.9.3.

None of the changes from 0.9.3 to 0.10.2 in brick/math affect its use in Laravel. The changes between versions of brick/math are minimal.

NB: @colincameron this change is also a win for users of https://github.com/pascaldevink/shortuuid for the same reason (brick/math dependency) 👍
