Upgrade ol-contextmenu to v5.4.0

Description

Upgraded the ol-contextmenu dependency to v5.4.0 (was v5.3.0 previously).

Motivation and Context

Currently, setting up a project with the peerDependencies as listed in the README results in a dependency conflict because ol=^9.0.0 is specified but ol-contextmenu 5.3.0 explicitly states ol<=8.x, which is fixed in the 5.4.0 version that @d-koppenhagen submitted and has since been released. Therefore the overrides workaround in the package.json is no longer necessary.

Edit: I just realised there was already an issue for this: #308

How Has This Been Tested?

Honestly I haven't tested this at all, but as the upstream change doesn't change anything than this very thing, it should be fine.™️

I hope I did everything correctly as this is the first time I commit to this project. I'm very happy to learn about anything I missed. My first intuition was to open another issue for it, but then I thought I could as well plunge forward and fix it myself :)
