[SPARK-52568][BUILD] Fix exec-maven-plugin version used by dev/test-dependencies.sh

### What changes were proposed in this pull request?

Fix `exec-maven-plugin` version used by `dev/test-dependencies.sh` to use the `exec-maven-plugin.version` defined in `pom.xml`, instead of the hardcoded old version(which does not work with Maven 4).

### Why are the changes needed?

Keep toolchain version consistency, and prepare for Maven 4 support.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Run `./dev/test-dependencies.sh`
```
...
++ build/mvn help:evaluate -Dexpression=exec-maven-plugin.version -q -DforceStdout
++ grep -E '[0-9]+\.[0-9]+\.[0-9]+'
Using `mvn` from path: /Users/chengpan/Projects/apache-spark/build/apache-maven-3.9.10/bin/mvn
+ MVN_EXEC_PLUGIN_VERSION=3.5.0
+ set +e
++ build/mvn -q -Dexec.executable=echo '-Dexec.args=${project.version}' --non-recursive org.codehaus.mojo:exec-maven-plugin:3.5.0:exec
...
```
And pass GHA.

### Was this patch authored or co-authored using generative AI tooling?

No.

Closes #51273 from pan3793/SPARK-52568.
