Add error handling/boundaries for plugins

Stopped plugins with errors crashing Headlamp:
- On plugin load (script syntax error, or other error)
- When components are rendering

Extracted plugin loading and executing into a Plugins component.

Wrapped ErrorBoundary around where plugins can insert components
into the app.

Plugins are initialized, not reset, so action renamed to match.

Allow to build without checking for updates

This patch loads environment variables from a .env file and ships the
file in the app as well, in order to allow different builds with minimal
changes to Headlamp's core.
Those options, when needed, are passed to the renderer process by IPC
through the recenly added appConfig message.

So these changes also only check for updates if the checkForUpdates
option in the app/packages.json is defined.

This patch replaces the appVersion IPC message for getting the app's
version with a new app config, so we can extend it to include more
items.

Add checks for exported common components

Fix exporting circular chart

Fix logo getting trimmed

When not defined, it will be just empty whereas before it was marked
as optional but being asserted.

It was being exported only as a default, and as such, was not getting
picked up when exporting from common/index.tsx.

plugins/examples: Update headlamp-plugin for all example plugins

It was getting shown within a material-ui SvgIcon but this component
is supposed to be used to display icons, not images.

Without it, the plugins fail to run.

Fix new version checks

app: Update electron and electron-builder

Apparently versions >16 of electron may end up showing artifacts due
to GPU issues in WSL2 but it works fine outside of it, and we need to
update dependencies.

Fix ActionButton color and width problems

The appVersion was being sent before the component in the renderer that
needs it was ready to act on it.

To prevent this, the app now sends the appVersion only when it receives
such a request.

This fixes the Create resource button being invisible.

frontend: Make the namespaces filter values occupy just one line

When multiple namespaces were selected, the input could show several
lines and that made the header for the contents very large vertically,
which didn't look good.

This patch changes how the namespaces are shown, so that only up to
a certain number of chars are visible for the namespace name and after
that it shows how many other namespaces are selected.

app: Add chocolatey spec + install script

charts: Bump Headlamp version to 0.11.0

This patch allows us to build a chocolatey package for Headlamp.
