all: nominate Zig 2024.05

[slimsag]

Periodically we nominate a new Zig nightly version to be the version that Mach targets, and begin the meticulous process of updating every Mach project to use that new version.

This is the tracking issue to do that for the next scheduled nomination (see the date in the issue title.)

You may have been linked to this issue because you sent a pull request to update a Mach project to use a new Zig API - if that is the case we do appreciate the PR and will look at merging it once this process begins. In the meantime, your PR may stay open for a while. You can either use a fork of the project, or use the version of Zig that Mach currently supports.

Update process

• It is time to begin (see date in issue title, we aim to begin this checklist between the 1st-4th of that month.)
• In machengine.org repository static/zig folder, wrench script nominate-zig-index-update nominate 2024.1.0-mach-wip has been ran and the index.json has been updated.
• #wrench automation (!wrench schedule-now update-zig-version) has created new pull requests to update the Zig version used in CI of all our projects, and it matches index.json.
• The Nomination history has a new section for the latest nightly Zig version which Wrench used in its PRs, with a warning at the top **IN-PROGRESS:** This version is currently being nominated, see [the tracking issue](https://github.com/hexops/mach/issues/1135) for details. Once everything looks good, the new Zig version is confirmed to be working with Mach, we will declare success, close the issue, and remove this in-progress warning..
