Remove:
```
__LATEST_COMPOSE_RELEASE_VERSION__
__KOTLIN_COMPOSE_VERSION__
System.getenv("COMPOSE_TEMPLATE_COMPOSE_VERSION")
```
They pollute templates/examples.
Now, all paths where we need to change the version are hardcoded in the script.
Usage:
```
./replace.sh 1.0.0-rc6
```
This script is planned to run on CI
In the future I will add support for changing Kotlin version
