[hotfix] Deep Lake fails on newer version due to hardcode (#6383)

Hot Fixes for Deep Lake [would highly appreciate expedited review]

* deeplake version was hardcoded and since deeplake upgraded the
integration fails with confusing error
* an additional integration test fixed due to embedding function
* Additionally fixed docs for code understanding links after docs
upgraded
* notebook removal of public parameter to make sure code understanding
notebook works

#### Who can review?
