fix: ignore diff for trailing dots in Record.route53 names

[erhancagirici]

Description of your changes

In Record.route53 resources, spec.forProvider.name accepts both foo.example.org. and foo.example.org. (with trailing dot) and they are semantically equal. However, upstream TF provider always store these in the state without trailing dots. This causes unnecessary diff when the configuration value has a trailing dot.

I have:

• Read and followed Crossplane's contribution process.
• Run make generate and committed the results (ideally in a separate commit).
• Not made any manual changes to generated files, and verified this with make check-diff.

How has this code been tested

Uptest failed due to a webhook issue, manually tested #1877 (comment)

Manual test:

1. Create the Route53 record with deletionPolicy: Orphan

apiVersion: route53.aws.upbound.io/v1beta1
kind: Record
metadata:
  name: example
spec:
  deletionPolicy: Orphan
  forProvider:
    name: www.mycompany.test.
    records:
    - "dev.upbound.io"
    ttl: 5
    type: CNAME
    zoneId: Z07016181LMZWWQUWB1ZB

2. After the resource is created successfully, delete the resource from the cluster.
3. Then apply the following YAML to import it:

apiVersion: route53.aws.upbound.io/v1beta1
kind: Record
metadata:
  name: example
  annotations:
    crossplane.io/external-name: Z07016181LMZWWQUWB1ZB_www.mycompany.test._CNAME
spec:
  forProvider:
    name: www.mycompany.test.
    records:
    - "dev.upbound.io"
    type: CNAME
    zoneId: Z07016181LMZWWQUWB1ZB

Without this fix, you see the following error:

  - lastTransitionTime: "2025-10-09T11:00:56Z"
    message: 'update failed: async update failed: refuse to update the external resource
      because the following update requires replacing it: cannot change the value
      of the argument "name" from "www.mycompany.test." to "www.mycompany.test"'
    reason: ReconcileError
    status: "False"
    type: Synced

With this fix, the resource was successfully imported:

  conditions:
  - lastTransitionTime: "2025-10-09T11:12:46Z"
    observedGeneration: 2
    reason: ReconcileSuccess

    reason: UpToDate

    type: Test
