Problem Description

user-agent processor with a user-agent as Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:128.0) Gecko/20100101 Firefox/128.0 produces versions with trailing .. The issue is made worse due to #116946 which causes the produced value to be mapped as a date if date detection and dynamic mapping are enabled.

Steps to Reproduce

PUT _ingest/pipeline/user_agent
{
  "description" : "Add user agent information",
  "processors" : [
    {
      "user_agent" : {
        "field" : "agent"
      }
    }
  ]
}
PUT testagentbug/_doc/my_id?pipeline=user_agent
{
  "agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:128.0) Gecko/20100101 Firefox/128.0"
}
GET testagentbug/_doc/my_id // The `user_agent.version` field has the value of `128.0.`

Expectation is for the user_agent.version to be correctly detected (without the trailing .)
