[SCM Integrations] Remove SCMIntegrationUUID from structs

[brandon-welsch]

Remove the field SCMIntegrationUUID on theses structs, they are not useful here :

type SCMRepoLinkCreateParams struct {
	AuthIntegrationUUID      *string `json:"auth_integration_uuid,omitempty"`
	SCMIntegrationUUID       *string `json:"scm_integration_uuid,omitempty"`   <===
	AutoDeployEnabled        *bool   `json:"auto_deploy_enabled,omitempty"`

type SCMRepoLink struct {
	AutoDeployEnabled        bool              `json:"auto_deploy_enabled"`
	SCMIntegrationUUID       string            `json:"scm_integration_uuid"`   <===
	AuthIntegrationUUID      string            `json:"auth_integration_uuid"`
