[Fleet] Fix "Learn More" link to open in new tab

[Copilot]

Summary

The "Learn More" link in the Fleet privileges callout was opening in the same tab instead of a new window, disrupting user navigation context.

Added target="_blank" to the EuiLink component rendering the documentation link. This aligns with the pattern used across all other external links in the Fleet plugin.

Change:

// Before
<EuiLink href={docLinks.links.fleet.roleAndPrivileges} external>

// After  
<EuiLink href={docLinks.links.fleet.roleAndPrivileges} external target="_blank">

Checklist

• Any text added follows EUI's writing guidelines, uses sentence case text and includes i18n support
• Documentation was added for features that require explanation or tutorials
• Unit or functional tests were updated or added to match the most common scenarios
• If a plugin configuration key changed, check if it needs to be allowlisted in the cloud and added to the docker list
• This was checked for breaking HTTP API changes, and any breaking changes have been approved by the breaking-change committee. The release_note:breaking label should be applied in these situations.
• Flaky Test Runner was used on any tests changed
• The PR description includes the appropriate Release Notes section, and the correct release_note:* label is applied per the guidelines
• Review the backport guidelines and apply applicable backport:* labels.

Identify risks

• No risks. Single attribute addition to existing link element with no logic changes.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• ci-stats.kibana.dev
  • Triggering command: /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node --no-experimental-require-module scripts/kbn bootstrap --quiet (dns block)
  • Triggering command: /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node --no-experimental-require-module scripts/kbn clean (dns block)
  • Triggering command: /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node --no-experimental-require-module scripts/kbn bootstrap --force-install (dns block)
• download.cypress.io
  • Triggering command: /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node /home/REDACTED/.nvm/versions/node/v22.17.1/bin/node index.js --exec install (dns block)

• iojs.org
  • Triggering command: /usr/bin/curl curl -q --fail --compressed -L -s REDACTED -o - (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
