feat(datadog): Add providers.talos.enabled option

charts/datadog/CHANGELOG.md

@@ -3,8 +3,8 @@
 ## 3.82.0
 
 * Added the configuration value `datadog.disablePasswdMount` to disable mounting the `/etc/passwd` path from the host filesystem. This option should be used when the underlying OS does not have these files (e.g., Talos OS).
-
 * Added the configuration value `datadog.disableDefaultOsReleasePaths` to disable mounting the default "os-release" file paths from the host filesystem (e.g., `/etc/redhat-release`, `/etc/fedora-release`, etc.). Note that this change does not affect the `datadog.osReleasePath` option. To avoid mounting the `/etc/os-release` host path, set the `datadog.osReleasePath` configuration value to an empty string. This option should be used when the underlying OS does not have these files (e.g., Talos OS).
+* Add `providers.talos.enabled` to simplify agent deployment configuration on Talos OS.
 
 ## 3.81.0
