#717)

* fix: cell selection in Firefox not working, fixes #714
- fixes issue #714

* tests: add Cypress with Firefox to CI workflow

* tests: use already serving http server

* tests: just testing Cypress with Chrome is enough

- update a few GitHub Actions plugins to their latest versions

- add a delay of a cycle to avoid screen flickering that we observed to be worst in Chrome and Salesforce. This small delay of 1 cycle is enough to remove the flickering
- the process is that when the grid is being scrolled horizontally, it has to change the scroll position of every other div container that might exist (preheader, headerrow, footer) and if we change the position at the same time as the grid scroll it can cause flickering

* feat(dataView): add option to apply row selection to all pages
- supersede #689, most Grid & DataView changes were kept with some small changes & fixes, also added more Cypress E2E tests
- when having pages and `syncGridSelection` is called with `preserveHiddenOnSelectionChange`,  clicking on Select All checkbox:
  - it will apply row selections on all rows
  - if nothing is selected and we filter data, then we click on Select All, it will apply row selections only to the item being filtered and if we remove filters then the Select All  is not expect to be selected

* chore: rollback slick.grid.js changes
- the changes to slick.grid.js should be applied in a different PR and there's also one opened for this

* chore: add selected rows ids to onSelectedRowIdsChanged

* chore: add option to apply grid row selection with setSelectedIds

* chore: rename option to better represent applying row selection to grid

* chore: change setSelectedIds option defaults
