fix: allow component-no-space in config schema

[Boulea7]

component-no-space is already declared as a boolean in ReleaserConfigOptions, but the root property allowlist marks it as false. As a result, otherwise valid top-level configurations are rejected by the published schema.

This allows the property at the root and adds schema tests for omitted, false, true, and invalid non-boolean values.

• Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Ensure the tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (the option is already documented)
