[Fleet] Integration UI design review cleanup

[jen-huang]

• In Kibana > Add data overview page, adjust the Fleet messaging
• In Kibana > Add data > module page (i.e. Apache logs), adjust the Fleet messaging
• Rename Kibana feature registration from "Fleet" to "Fleet and Integrations"
• In Integrations > Integration details > Assets, expand first panel by default
• In Integrations > Integration details > Assets, pluralize and sentence case all asset types: Dashboards, Saved searches, Visualizations, Views
  • This will probably affect the assets list on Overview page, which is fine
• In Kibana > Global search bar, change "Package" to "Integration" and type:package to type:integration
• In Integrations > Integration details > Policies > Add agent flyout, reword Step 2 title and description
  • JS: Set to Select enrollment token. Select which enrollment token to use when enrolling agents.
• In Integrations > Integration details > Policies > Add agent flyout, automatically expand enrollment tokens options

For "In Kibana > Add data overview page, adjust the Fleet messaging", what do we want for the wording here? I took a "common sense" pass and simply removed the "Beta" wording, e.g.

Wondering if the "New!" prefix should also be removed.
