Created gradle configurations aren't correctly configured

[timocov]

According to official gradle docs https://docs.gradle.org/current/userguide/declaring_configurations.html#sec:configuration-flags-roles:

Out of canBeResolved, canBeConsumed and canBeDeclared flags "Configurations should only have one of these flags enabled.". When configurations get created in

smithy-gradle-plugin/smithy-base/src/main/java/software/amazon/smithy/gradle/SmithyBasePlugin.java

Lines 123 to 128 in a770f94

	Configuration smithyBuildConfig = configurations.maybeCreate(
	SmithyUtils.getSmithyBuildConfigurationName(sourceSet));
	smithyBuildConfig.setVisible(false);
	smithyBuildConfig.setTransitive(true);
	smithyBuildConfig.extendsFrom(configurations.getByName(compileOnlyConfigurationName));
	smithyBuildConfig.setDescription("Build-time smithy dependencies for " + sourceSet + ".");

they don't have these flags configured, which means that by default they have all 3 flags set to true (according the gradle's source code).

It feels like smithyBuild configurations should be only marked as canBeResolved and all other flags should be set to false?

I'm happy to contribute if you're happy with the proposal (with the caveat it seems that it might bump the min supported gradle version to 8.3, but considering that you're building against 8.14 already it shouldn't be a problem?).
