<summary>⚙ Adjust future updates</summary>

Add these to your `.scala-steward.conf` file to ignore future updates of
these dependencies:
```
updates.ignore = [
  { groupId = "software.amazon.awssdk", artifactId = "bedrockruntime" }
]
```
Or, add these to slow down future updates of these dependencies:
```
dependencyOverrides = [
  {
    pullRequests = { frequency = "30 days" },
    dependency = { groupId = "software.amazon.awssdk", artifactId = "bedrockruntime" }
  }
]
```
