Describe the bug

There are various issues with the documentation links at https://github.com/GoogleCloudPlatform/spring-cloud-gcp#spring-framework-on-google-cloud.

1. The 'Spring Framework on Google Cloud 7.0.0 (Latest)' link mentions version 7.0.0 being the latest version, while 7.1.0 is the latest. The actual link does point to the documentation for version 7.1.0, which is indeed currently the latest.
2. The 'Javadocs 7.0.0' link should be a link for the latest version (7.1.0), but neither https://googleapis.dev/java/spring-cloud-gcp/7.0.0/index.html nor https://googleapis.dev/java/spring-cloud-gcp/7.1.0/index.html seem to be available, so that would need to be fixed first.
3. The 'Spring Framework on Google Cloud 6.2.3' link should be for the latest 6.x version, which is currently 6.3.1.
4. The 'Javadocs 6.2.3' link should be for the latest 6.x version (6.3.1, but https://googleapis.dev/java/spring-cloud-gcp/6.3.1/index.html doesn't seem to be available, so that would need to be fixed first.
5. The 'Spring Framework on Google Cloud 5.12.3' link should be for the latest 5.x version, which is currently 5.13.1.
6. The 'Javadocs 5.12.3' link should be for the latest 5.x version (5.13.1), but https://googleapis.dev/java/spring-cloud-gcp/5.13.1/index.html doesn't seem to be available, so that would need to be fixed first.
7. The 'Spring Framework on Google Cloud 3.9.5' link should be for the latest 3.x version, which is currently 3.9.7.
8. The 'Javadocs 3.9.5' link should be for for the latest 3.x version (3.9.7), but https://googleapis.dev/java/spring-cloud-gcp/3.9.7/index.html doesn't seem to be available, so that would need to be fixed first.

I've reported similar issues with these links before, so maybe some adjustments need to be made to the Spring Cloud GCP release process to ensure that these links are kept up-to-date?
