Spring transitive dependencies conflict

Describe the bug Seems that the version included by shedlock clashes with spring-boot already in my project.

Which version do you use: 4.15.1
Which Lock Provider: shedlock-provider-jdbc-template
ShedLock configuration:

Application.kt

@EnableScheduling
@EnableSchedulerLock(defaultLockAtMostFor = "10m")
class Application

fun main() {
  runApplication<Application>()
}

ShedLockConfiguration.kt


import net.javacrumbs.shedlock.core.LockProvider
import net.javacrumbs.shedlock.provider.jdbctemplate.JdbcTemplateLockProvider
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.jdbc.core.JdbcTemplate
import java.util.TimeZone
import javax.sql.DataSource

@Configuration
class ShedlockConfiguration {

  @Bean
  fun lockProvider(dataSource: DataSource): LockProvider =
    JdbcTemplateLockProvider(
      JdbcTemplateLockProvider.Configuration.builder()
        .withJdbcTemplate(JdbcTemplate(dataSource))
        .withTimeZone(TimeZone.getTimeZone("Europe/Madrid"))
        .build()
    )
}

**Expected behavior**
Should not give any exceptions.

**Actual behavior**
It fails because the library already imports transitively spring dependencies.

**Temporal fix**
In your `build.gradle`:

```gradle
    // Shedlock
    def shedlockVersion = "4.15.1"
    implementation("net.javacrumbs.shedlock:shedlock-spring:$shedlockVersion") {
      exclude group: "org.springframework", module: "spring-context"
    }
    implementation("net.javacrumbs.shedlock:shedlock-provider-jdbc-template:$shedlockVersion") {
      exclude group: "org.springframework", module: "spring-jdbc"
    }
