Make FBC method a default in documentation

The documentation is updated to reflect FBC changes and suggest using
FBC for all operators. Hopefully this will increase an adoption of the
FBC method.

+The `fbc.enabled` flag enables the [File-Based catalog](./fbc_workflow.md) feature. It is highly recommended to use the FBC mode in order to have better control over the operator's catalog.

+### `fbc.version_promotion_strategy`
+The `fbc.version_promotion_strategy` option defines the strategy for promoting the operator into a next OCP version. When a new OCP version becomes available an automated process will promote the operator from a version N to a version N+1. The `fbc.version_promotion_strategy` option can have the following values:
+
+- `never` - the operator will not be promoted to the next OCP version automatically (default)
+- `always` - the operator will be promoted to the next OCP version automatically
+- `review-needed` - the operator will be promoted to the next OCP version automatically, but the PR will be created and the reviewers will be asked to review the changes
