Fix the version io.micrometer mismatch between libs.versions.toml and the lib versions in the binary distribution

### Describe the bug

The version mismatch is confusing and make it hard to update the license. It doesn't impact the runtime though, as their versions are consistent.

libs.versions.toml:
```
micrometer-bom = { module = "io.micrometer:micrometer-bom", version = "1.15.1" }
```

For both `polaris-admin` and `polaris-server`, the final resolved versions are 1.14.7 for the main branch. (It's 14.6 for the branch `release/1.0.x`, which aligns with @jbonofre 's observation.)
```
ygu@FM4LQ4GJ90 polaris-bin-1.1.0-incubating-SNAPSHOT % ls admin/lib/main | grep io.micrometer
io.micrometer.micrometer-commons-1.14.7.jar
io.micrometer.micrometer-core-1.14.7.jar
io.micrometer.micrometer-observation-1.14.7.jar
ygu@FM4LQ4GJ90 polaris-bin-1.1.0-incubating-SNAPSHOT % ls server/lib/main | grep io.micrometer
io.micrometer.micrometer-commons-1.14.7.jar
io.micrometer.micrometer-core-1.14.7.jar
io.micrometer.micrometer-observation-1.14.7.jar
io.micrometer.micrometer-registry-prometheus-simpleclient-1.14.7.jar
```

Start by comparing the micrometer entry in libs.versions.toml with the resolved JAR versions under admin/lib/main and server/lib/main. Trace how the binary distribution resolves those dependencies for the main branch and confirm that both polaris-admin and polaris-server use the version declared in libs.versions.toml.
