Fix :core:shadedClasses failure (#6514)

Motivation:

':core:shadedClasses' fails when JaCoCo report is enabled by
`-Pcoverage` because `shadedClasses` is only used in the JaCoco task.

```java
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':core:shadedClasses'.

It seems that the `archiveClassifier.set('shaded')` configuration used
when upgrading Gradle 9 is causing the problem.
Based on the following two configurations, the path of archiveFile
becomes `<artifact>-untrimmed-<version>-shaded.jar`.
https://github.com/line/armeria/blob/7148df07f3a7fe7cb4640fb1ca761cbaca8b347f/gradle/scripts/lib/java-shade.gradle#L28

This is then renamed to `<artifact>-shaded-<version>-shaded.jar` by
`trimShadedJar` task. However, since the input file of `shadedClasses`
is `<artifact>-<version>-shaded.jar`, the task fails to fine the jar
file.

Modifications:

- Generate the output file name correctly by removing `untrimmed` infix
from the output jar file instead of renaming it to `shaded`.
- Miscellaneous) Make `publishJarPublicationToMavenLocal` depend on
`shadedTask` or `trimShadedJar` to run `publishToMavenLocal`
successfully.

Result:

`:core:shadedClasses` runs correctly
