bump emberjson for 25.5

Checklist

• My recipe.yaml file specifies which version(s) of MAX is compatible with my project (see here for an example). If not, my package is compatible with both 24.5 and 24.6.
• License file is packaged (see here for an example).
• Set the build number to 0 (for new packages, or if the version changed).
• Bumped the build number (if the version is unchanged).

suggestion: use mojo-compiler package now that it's released instead.
suggestion: add a requirements.build section that also specifies mojo-compiler.

Good call! What's the purpose of adding the requirements.build entry?

[sstadick]

Just completeness! https://pixi.sh/latest/reference/pixi_manifest/#host-dependencies

build - things that are executed at build time (compilers)
host - stuff that is linked against
run - stuff that you need around at runtime

We link against stuff supplied by the mojo-compiler package so technically we don't need to specify it as a build dep, but it makes the packages more robust to tooling changes by prefix.

Makes sense thanks!

@bgreni is there a reason you picked the mojo pkg over mojo-compiler for the run and host? mojo bundles in the LSP, formatter, and debugger. https://forum.modular.com/t/mojo-now-available-in-conda-as-a-standalone-package/2052

Learning as I go here, but it seems like mojo test does not work correctly if just the mojo-compiler package is installed. So for tests specifying mojo is needed.
