[KED-1833] Front End for hook implementation for kedro-viz

[ptadas]

Description

This PR adds FE changes to Hook implementation for kedro-viz

Development notes

Some code in package/kedro_viz/server.py, package/kedro_viz/specs.py and package/tests/test_server.py is from the aforementioned PR.

Please ignore the styling for now.

Updated:

• Change the node color (can be some other indicator) whenever a hook for a dataset exists
• When right click on the node, replace the default context menu, with the one for hooks (at this point not entirely sure what other hooks will exist, thus assume all will have same functionality)

Wow, this is really fast turnaround :D I remember when chatting with @MerelTheisenQB, we thought of having the new side panel extensible with "slots" that plugins can populate through hooks. Otherwise, what would happen if there is another plugins wanting to display external links? Would it be another tooltip?

I think the best way forward is to have a behaviour based hooks. ie have kedro-ge add data to node['hooks']['context_menu'] + maybe additional behaviour options within the hook, ie node['hooks']['context_menu']['href'], but open to suggestions! I guess we don't need to overcomplicate the nested structure for the first hooks, as we can always update when new hooks get added

Hi everyone! We've appreciated the careful thought that went into this PR. However, I'm going to close this PR on the basis that when we look into the Kedro-GE integration, we'll pick up this work again. I also note that at least this information is stored somewhere.
