fix: generate *float64 with convert import path

[cristiGuranIonos]

Description of your changes

Float64 pointer fields are not generated correctly using the latest version of corssplane-tools:
Example:

 mg.Spec.ForProvider.Lan = ptr.ToFloatPtrValue(rsp.ResolvedValue)

Where the import is :

ptr "k8s.io/utils/ptr"

I have:

• Read and followed Crossplane's [contribution process].
• Run make reviewable test to ensure this PR is ready for review.

How has this code been tested

Replace in go.mod for provider-upjet-ionoscloud with the local copy with the changes. Test that the code is generated correctly.

go mod vendor
make generate
make run

Ran tests in resolvers_test.go . These tests were failing before I made any changes:

		          		rsp, err = r.Resolve(ctx, reference.ResolutionRequest{
        - 			CurrentValue: convert.FromPtrValue(mg.Spec.ForProvider.CustomConfiguration),
        + 			CurrentValue: mg.Spec.ForProvider.CustomConfiguration,
          			Extract:      Configuration(),
          			Reference:    mg.Spec.ForProvider.CustomConfigurationRef,
          	... // 7 identical lines
          			return errors.Wrap(err, "mg.Spec.ForProvider.CustomConfiguration")
          		}
        - 		mg.Spec.ForProvider.CustomConfiguration = convert.ToPtrValue(rsp.ResolvedValue)
        + 		mg.Spec.ForProvider.CustomConfiguration = rsp.ResolvedValue
          		mg.Spec.ForProvider.CustomConfigurationRef = rsp.ResolvedReference

I fixed those errors, but maybe someone can take a closer look at that field.

Note: There is another solution to use convert path for both IsPointer and IsFloatPointer, but I saw that convert.FromPtrValue in convert.go is deprecated in favor of ptr.Deref.
