Issue Description

In the README file, there are several instances indicating // TODO: fix links, which suggests that the documentation contains broken or incomplete links. This can lead to confusion for users trying to navigate to relevant sections for more information on various features and authentication methods.

Suggested Solution

1. Review all the links mentioned under the Spring Cloud Vault Config Client section.
2. Verify that they are correctly pointing to the respective sections in the documentation.
3. Update the links accordingly to ensure they direct users to the intended documentation pages.

By correcting these links, we can improve the user experience by ensuring seamless navigation within the documentation.
