Replace wildcard and match_only_text types to keyword

[AlexRuiz7]

Description

Due to a bug in OpenSearch Dashboards not rendering supported types properly in Discover and other places of the UI, we need to change the mappings for every Wazuh index replacing wildcard and match_only_text types with keyword|text.

Related issues:

• [BUG] process.command_line field mapping is not properly picked up by the dashboard #585

Functional requirements

• None of the stateful indices use wildcard or match_only_text field types.
• None of the stateless (alerts, commands) indices use wildcard or match_only_text field types.

Implementation restrictions

• The changes must be performed by updating our generation script, so the replacements are automated.
• Consider using text instead of keyword for better search behavior.

Plan

• Patch the generate.sh script.
• Regenerate the mappings.
• Update the index templates for the setup and command-manager plugins.

No wildcard or match_only_text fields are present in the plugins mappings anymore:

$ grep -ERl 'wildcard|match_only_text' setup/src/main/resources/
