Mainly for the new nodejs 16 LTS, but also pg 14, and linux LTS.

Because Nodejs 16 is now LTS node, and it has various improvements
including better support for javascript modules.

frontend: Make workload details go back to the correct list view

Fix UI warnings

frontend: Fix warning color's contrast on dark theme

frontend: Check for a pod's conditions before using them

Those were disableBackdropClick and disableEscapeKeyDown.

This prevents a warning in the version of material-ui currently used.

Better info for workloads

frontend: Fix applying non-grouped API resources

This prevents the issue of calling a function on a variable that may
be undefined.

Some APIs do not have a group and we were parsing the YAML added to
the creation dialog in a way that it expected to have a group.

These include the owned pods, containers, and details view plugin
renderer sections.

This will be useful to understand e.g. why pods are pending.

This allows us to show the controlled jobs, the schedule with a
human-readable description, etc.

The last scheduled time was not using the "time ago" way and therefore
was very confusing. This patch also adds an icon to the schedule
(cron) with a description of it on hover.

There was a bug where such statuses were being shown with the warning
theme.

plugins: Allow to use shared modules with the import syntax

Limit the window size for desktop app, setup jest test framework

frontend: Use the current theme for the ConfigMaps' editor

Fix windows app not closing server.exe on quit

There's a margin in WSL because it has problems placing
full size windows.

This is useful as it is but also will satisfy the linter (which
complains that the template plugin's registry argument is not
used).
