Dynatrace platform token

[agardnerIT]

The existing Dynatrace pattern is correct - for standard API access tokens
But Dynatrace also has a "platform token". The pattern for these is:

- pattern:
      name: Dynatrace token
      regex: dt0[a-zA-Z]{1}[0-9]{2}\.[A-Z0-9]{8}\.[A-Z0-9]{64}
      confidence: high

Example: dt0s16.ABCD1ABC.ABCD1235IX6B7DHBSZZH6NF7U53WJPUBT4SUQYCND35VMV7CX67TAJRO2GBD222A
