Observability Overview points to old devant documentation

[pcnfernando]

The links within the Observability Overview(https://wso2.com/integration-platform/docs/deploy-operate/observe/observability-overview) section are currently pointing to the outdated devant documentation

I checked the current page/source and the stale-link report still reproduces.

Fresh verification:

• This issue is still open/unassigned with no prior comments.
• I did not find an open PR touching en/docs/deploy-operate/observe/observability-overview.md or matching devant / monitoring-and-insights; the open restructure PR Restructure Deploy and Manage sections  #522 does not include this observability page.
• The live page still contains exactly one devant link:
  https://wso2.com/devant/docs/monitoring-and-insights/observability-overview/
• The source is en/docs/deploy-operate/observe/observability-overview.md, line 46, in the comparison table row for WSO2 Integration Platform.
• The devant URL returns 200, so this is not a dead-link failure; it is a stale/wrong-product-context link from the Integration Platform docs to the older Devant docs.

The likely fix is to update that table row's WSO2 Integration Platform href to the intended current Integration Platform observability target, or make it non-linked if this overview page is itself the intended target.
