For the submodules that have some kind of release (tags), they were
updated up to the most recent release. Otherwise, the submodule was
updated to the latest commit.
This updates the submodules for autosuggestions, completion,
syntax-highlighting and the prompts async, powerlevel9k and pure.
All submodules that have TAGs/Releases were updated to their latest
TAG/release, except for syntax-highlighting because it's latest
release/TAG is from more than one year ago, and the project seems to be
well maintained but without releases.
