feat: multi-select rows with shift key [WD-8506]

[mas-who]

Done

• Add ability to multi select rows if the shift key is pressed.

QA

1. Run the LXD-UI:
   • On the demo server via the link posted by @webteam-app below. This is only available for PRs created by collaborators of the repo. Ask @mas-who or @edlerd for access.
   • With a local copy of this branch, run as described here.
2. Perform the following QA steps:
   • Check normal select rows and bulk actions on the instance list and images list tables still work as expected
   • Check that multi select rows with shift key pressed works as expected i.e. select one row, the hold down shift key and select another row, all rows in between should be selected.
