Remove all non-legacy usage of Zepto

[akhenry]

Is your feature request related to a problem? Please describe.
Zepto is a performant drop-in replacement for JQuery and Angular's $ function. It was used pretty extensively in our legacy codebase, but there is also some usage in our current codebase.

Describe the solution you'd like
All usage of zepto in our current codebase (ie. everything under /src/) should be replaced with native JavaScript API calls.

The following usage of Zepto in non-deprecated code shoulld be removed:

• The "Simple" Indicator
• The URL Indicator plugin,
• Tests for the Autoflow tabular plugin. These tests are currently disabled. Could we please re-enable them as part of this issue?

Additional context
There is also usage of Zepto in our legacy codebase (ie. under "platform"), and in Summary Widgets but this code is deprecated and will be removed under a separate task.

We should also remove exports-loader as a part of this PR

Testing Notes (taken from #5159 (comment))

Plugins affected:

Summary Widget
URL Indicator Plugin

To test, all functionality of the listed plugins should remain the same prior to these changes.

'Add condition' functionality under summary widget is bugged prior to these changes. At a glance, the refreshConditions function does not seem to be using the updated config object from the corresponding initCondition function in the Rule.js file.

Note that we may need to temporarily re-enable the creation of summary widgets to test this.

We need to enable summary widgets to test this issue.

Will need to create a local viper-openmct install based on release/2.0.5 with summary widgets enabled

Verified fixed by importing attached JSON file that includes a summary widget. No need to enable creation of summary widgets
