[O11y][Oracle WebLogic] Lens migration for visualizations to kibana version 8.4.0

[harnish-elastic]

• Enhancement

What does this PR do?

• Migrate visualizations to lens for Oracle WebLogic integration package

• Statistics for Oracle WebLogic Lens migration:

Oracle WebLogic dashboards	Before Migration		After Migration
	Lens	Visualization	Lens	Visualization
[Metrics Oracle WebLogic] Deployed Application	5	2	7	0
[Logs Oracle WebLogic] Logs Overview	3	8	7	4
[Metrics Oracle WebLogic] ThreadPool	8	1	9	0
	16	11	23	4

• 4 visualizations are markdown visualizations which won't be converted to lens.

• Updated TagCloud visualizations to the horizontal bar chart. For that, changed the visualization name from Request Endpoint [Logs Oracle WebLogic] to Top values of Request Endpoint [Logs Oracle WebLogic]

Checklist

• I have added an entry to my package's changelog.yml file.
• I have verified that panels are populated with data.
• I have verified that panels are not distorted after being migrated to lens.
• I have updated screenshots of dashboard.
• I have verified that data count are matching and panel aggregations are same as before.

Author's checklist

• Migrated panels should be removed from visualization folder.
• Migrated visualizations are populating in current Kibana version 8.4.0 itself.

Waiting for more clarification

[agithomas]

Any reason why coreMigrationVersion and migrationVersion.lens are different?. Are export dashboard method consistently used and no manual overriding done?

We are using elastic-package export dashboards command while exporting the dashboards. We are not manually overriding it. We are not sure of above two fields difference.
