Updating bazelbuild/platforms

WARNING: These are what worked last time. Reality might be different.

Step 1: Make the release

• Pick a new version number

• Update version.bzl

• Run distro/makerel.sh

• Go to the Releases page

• Draft a new release

  • Name the release with a version number
  • Use the version number as the title
  • Copy the description that makerel.sh produced to the description field.
  • upload the generated tar file

• use https://github.com/bazelbuild/continuous-integration/blob/HEAD/mirror/mirror.sh to mirror the file

Step 2: Update Bazel

• Edit distdir_deps.bzl
• Merge the PR

Sample diff:

diff --git a/distdir_deps.bzl b/distdir_deps.bzl
