This allows us to match the version the binaries use more closely.

For example, chromedriver darwin (binary) reports the following:

~~~bash
chromedriver --version
ChromeDriver 131.0.6778.85 (3d81e41b6f3ac8bcae63b32e8145c9eb0cd60a2d-refs/branch-heads/6778@{#2285})
~~~

while on Linux, where we build chromedriver based on the chromium
derivation from source and control the string ourselves:

~~~bash
chromedriver --version
ChromeDriver 131.0.6778.85 (131.0.6778.85-refs/heads/master@{#0})
~~~

With this commit, the version string now reports:

~~~bash
chromedriver --version
ChromeDriver 131.0.6778.85 (3d81e41b6f3ac8bcae63b32e8145c9eb0cd60a2d-refs/tags/131.0.6778.85@{#0})
~~~

This may seem like a small and unimportant detail, but turns out an
internal function within chromedriver depends on the git hash.

See https://chromium.googlesource.com/chromium/src/+/131.0.6778.85/chrome/test/chromedriver/chrome/browser_info.cc#172

This caused the tests of one package (single-file-cli) that use
selenium with chromium and chromedriver to fail in 24.05.

Only in 24.05, because 24.11 and unstable removed their test dependency
on chromedriver because it wasn't available for aarch64-linux at that
time.
