Subject: [PATCH 05/23] text(e2e): give git tests consistent commit id

gitGraph render tests are currently using random commit ids,
which causes visual regression tests to fail.

I couldn't find a way to make the random commit IDs consistent
(JavaScript/Cypress doesn't seem to have a random.seed() function),
so I've just hardcoded all the commit ids.

Subject: [PATCH 07/23] fix(flowchart-v2): fix arrowMarkerAbsolute=true

The if-check for arrowMarkerAbsolute in the flowchart-v2 code is in
dagre-wrapper. Unfortunately, I can't seem to find a way to find the
local conf (e.g. the one set via `flowRenderer.setConf()`, so instead
I'm using global mermaid config from `src/config`.

Flowchart v1 arrowMarkerAbsolute=true is still broken, but I'm not
really sure how to fix that.

Subject: [PATCH 08/23] chore: upgrade cypress to v10

Cypress v10 had some minor breaking changes,
(e.g. the cypress/plugins folder dissapeared)
so I had to change some things.

It looks like the Cypress was previously reverted in [dee9cfe][1],
due to applitools not working properly,
but I think my changes fix this, so it should be okay.

I've removed the coverage upload bit, since although the
[@cypress/code-coverage][1] plugin is pretty easy to setup,
it requires babel, which we're about to remove and replace
with ESBuild.

Subject: [PATCH 14/23] ci(e2e-applitols): add applitools CI action

Adds a [`workflow_dispatch`][1] GitHub Actions CI workflow
that performs an E2E Cypress rendering test with Applitools
integration.

If the APPLITOOLS_API_KEY secret is not set, this action fallsback to
just doing a normal E2E Cypress test without Applitools support.

-By default, the cherry-picked commit from commit with id `A` will be labeled `cherry-pick:A`. You can provide your own custom tag instead to override this behavior, using the same syntax as the `commit` keyword:
