Fix hardcoded language in Inactivity notification approval flows

[Copilot]

Problem

Inactivity notification flows ignored the admin_AdmineMailPreferredLanguage environment variable and always sent approval emails in English. Variable initialization hardcoded "en-US" instead of reading the parameter.

Changes

Modified flows:

• AdminInactivitynotificationsv2StartApprovalforFlow
• AdminInactivitynotificationsv2StartApprovalforApps

Before:

{
  "name": "varAssigneePreferredLanuguage",
  "type": "string",
  "value": "en-US"
}

After:

{
  "name": "varAssigneePreferredLanuguage",
  "type": "string",
  "value": "@parameters('Admin eMail Preferred Language (admin_AdmineMailPreferredLanguage)')"
}

Impact

• Honors configured language for approval emails (e.g., es-CO, fr-FR)
• Defaults to en-US when environment variable not set
• Backward compatible
