Added new input property to enable lazy loading

[ericf-axosoft]

Description

• Added new input property to enable lazy loading to be in sync with new changes of the GK Graph (see task for more details: https://github.com/gitkraken/GitKrakenComponents/issues/301)

Notes

• Works with dependant PR: https://github.com/gitkraken/GitKrakenComponents/pull/300
• For now, I left this PR as draft until changes related with the GK Graph are merged as we need to do a bump of that dependency in GitLens side.

@ericf-axosoft I think we can close this PR now since this client-side change is no longer needed.

The component-side PR (merged) is now using an existing prop to control lazy loading: https://github.com/gitkraken/GitKrakenComponents/pull/300
