URL: https://github.com/apache/pulsar/pull/23337
### Motivation
building a docker image with this command will fail.
```
mvn package -Pdocker,-main -am -pl docker/pulsar -DskipTests
```
error message is
```
[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.45.0:build
(default) on project pulsar-docker-image: Execution default of goal
io.fabric8:docker-maven-plugin:0.45.0:build failed: Given Docker name
'apachepulsar/pulsar:4.0.0-SNAPSHOT-${git.commit.id.abbrev}' is invalid:
[ERROR] * tag part '4.0.0-SNAPSHOT-${git.commit.id.abbrev}' doesn't match
allowed pattern '^[\w][\w.-]{0,127}$'
[ERROR] See http://bit.ly/docker_image_fmt for more details
```
### Modifications
Fix the problem by revisiting the `git-commit-id-plugin` configuration in
`docker/pom.xml` file.
Removing `<runOnlyOnce>true</runOnlyOnce>` fixes the problem.
