chore: Upgrade Gradle to v9, upgrade other plugins (#2158)

### 📝 Description

Ahead of the Spring/Spring Boot upgrade, we need to move to a version of
Gradle that supports Java 25.

To that end, this PR upgrades to Gradle from v8.8 to v9.4.0, which is
the latest version of Gradle:
https://docs.gradle.org/current/userguide/compatibility.html

As part of this, we also need to upgrade the Gradle plugins.

#### Changes

| Component | Old Version | New Version | Release Notes |
|---|---|---|---|
| Detekt | `1.23.7` | `2.0.0-alpha.2` | [detekt v2
changelog](https://detekt.dev/changelog-2.0.0) |
| Ktlint Gradle Plugin | `12.1.2` | `14.2.0` | [ktlint-gradle
releases](https://github.com/JLLeitschuh/ktlint-gradle/releases) |
| Maven Plugin Development Plugin | `0.4.3` | `1.0.2` |
[maven-plugin-development
releases](https://github.com/gradlex-org/maven-plugin-development/releases)
|

#### Plugin ID / Coordinate Migration

- Detekt plugin ID: `io.gitlab.arturbosch.detekt` -> `dev.detekt`
- Detekt plugin dependency:
`io.gitlab.arturbosch.detekt:detekt-gradle-plugin` ->
`dev.detekt:detekt-gradle-plugin`
- Maven plugin development ID:
`de.benediktritter.maven-plugin-development` ->
`org.gradlex.maven-plugin-development`

#### Detekt Config Migration

- Removed legacy `build.weights.comments`.
- Renamed deprecated/invalid keys to Detekt 2 equivalents:
  - `CommentOverPrivateFunction` -> `DocumentationOverPrivateFunction`
- `LongParameterList.functionThreshold` ->
`LongParameterList.allowedFunctionParameters`
- `TooManyFunctions.thresholdInInterfaces` ->
`TooManyFunctions.allowedFunctionsPerInterface`
- `TooManyFunctions.thresholdInClasses` ->
`TooManyFunctions.allowedFunctionsPerClass`
- `TooManyFunctions.thresholdInFiles` ->
`TooManyFunctions.allowedFunctionsPerFile`
- `ComplexInterface.threshold` -> `ComplexInterface.allowedDefinitions`
  - `FunctionMaxLength` -> `FunctionNameMaxLength`
