Add the defaultDataPlaneEnabled.linux chart value and render it as the unconditional Operator Linux ADP flag. Document CRD precedence and Windows scope, and cover the default and explicit false renderings.
Describe the default Linux ADP behavior and the chart and CRD-level opt-out paths in the unreleased Operator chart changelog entry.

- revert changelog for datadog-operator (no-version-bump) - update readme for datadog-operator
Restore the current chart version and registryMigrationMode documentation after no-version-bump automation regenerated the README with unrelated changes.
- update readme for datadog-operator
Use the environment-variable transport so charts remain installable with the currently pinned Operator image, which predates the command-line flag and safely ignores an unknown environment variable.
Document that the Linux ADP default applies to Agent 7.81 and later, while explicit workload configuration remains available for older Agent images.

What this PR does / why we need it:
Enables the Agent Data Plane by default for Linux Operator-managed workloads by setting
defaultDataPlaneEnabled.linux: truein thedatadog-operatorchart. The chart passes that value to the Operator asDD_DEFAULT_DATA_PLANE_LINUX_ENABLED.The Operator keeps CRD configuration and the legacy opt-out annotation authoritative, so individual workloads can opt out with
spec.features.dataPlane.enabled: false.Which issue this PR fixes
(optional, in `fixes #(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged)
Special notes for your reviewer:
2.26.0-dev.5and added the corresponding changelog entry.Checklist
