[Improvement] use incubating version in docs

[mchades]

What would you like to be improved?

Gravitino has become an Apache Incubator project since version 0.6.0, so it is necessary to follow the Apache versioning convention like 0.6.0-incubating instead of 0.6.0.

How should we improve?

visit all docs and update to incubating version after 0.6.0. Such as: https://github.com/apache/gravitino/blob/344e98df063548232f08a45a22fa06ebc26f6583/docs/how-to-use-gvfs.md?plain=1#L338-L348

should change the Since version column value to:
