Toolchains are selected via toolchain resolution. The name of the repository is irrelevant in this context. A better approach is to support registering multiple versions and using constraints to let the user pick between different versions. BREAKING CHANGE: The zig module extension no longer accepts a name attr.
The name attribute is no longer used
For backward compatibility
This allows a user to select among multiple different Zig SDK versions via build flags or transitions and to select based on the Zig SDK version or configure target compatibility with a specific version.
Toolchain resolution proceeds in the order in which toolchains are registered. When toolchains are registered through a wildcard label, such as `:all`, then their order is determined by lexicographical order. Add numerical prefixes to ensure that the user defined order is respected.

Support the registration and selection between multiple different Zig SDK versions.
