Change plugin-utilities dependency declaration

**!!!Actions required!!!**
We have published current [plugin-utilities](https://github.com/JetBrains-Research/plugin-utilities) lib version from master branch to space maven repository and in a week planning to modify api (so master branch will become invalid). Please, replace plugin-utilities lib git-based installation in your [build.gradle.kts](https://github.com/JetBrains-Research/PyNose/blob/master/build.gradle.kts#L32-L46) with (standard dependency declaration) by adding space repository and declaring required dependencies:
```
repositories {
maven(“https://packages.jetbrains.team/maven/p/big-code/bigcode”)
}

dependencies {
implementation(“org.jetbrains.research:plugin-utilities-core:1.0")
implementation(“org.jetbrains.research:plugin-utilities-test:1.0")
implementation(“org.jetbrains.research:plugin-utilities-python:1.0")
}
```
