chore(docker): update etcd config

[SkyeYoung]

Description

What:

This PR has updated the configuration of etcd in the docker folder.

This is solved the #12300 (comment)

How:

Mainly update the version, and removed an attribute user that would cause an error.

Why:

To allow .github/workflows/push-dev-image-on-commit.yml run in CI environment of arm64 runner. And the old etcd lacks support for arm64.

For compatibility:

Although there is no direct compatibility test here, but:

1. This measure has been verified in apisix-dashboard for a long time
   1. I mainly use m-series macbooks for development
   2. All dashboard e2e tests can be run based on this version of etcd
2. It has already been tested in PR fix(workflow): use runners with different architectures instead of QEMU #12322 and passed CI on both architectures.

Which issue(s) this PR fixes:
