refactor(API): refactor secret creation and update functionality (#26751)

According to the GitHub API Spec:
https://docs.github.com/en/rest/actions/secrets?apiVersion=2022-11-28#create-or-update-an-organization-secret

Merge the Create and Update secret into a single API.

- Remove the `CreateSecretOption` struct and replace it with
`CreateOrUpdateSecretOption` in `modules/structs/secret.go`
- Update the `CreateOrUpdateOrgSecret` function in
`routers/api/v1/org/action.go` to use `CreateOrUpdateSecretOption`
instead of `UpdateSecretOption`
- Remove the `CreateOrgSecret` function in
`routers/api/v1/org/action.go` and replace it with
`CreateOrUpdateOrgSecret`
- Update the Swagger documentation in
`routers/api/v1/swagger/options.go` and `templates/swagger/v1_json.tmpl`
to reflect the changes in the struct names and function names
