ops does not support HTTP_PROXY and HTTPS_PROXY env var

- [x] I have searched the [issues](https://github.com/apache/openserverless/issues) of this repository and believe that this is not a duplicate.

### Ⅰ. Issue Description
Since we are using the go git library it is supposed it supports the standard environment variables HTTP(S)_PROXY ... but it does not.

### Ⅱ. Describe what happened

seth the variables, and try ops -update... error!

### Ⅲ. Describe what you expected to happen

it should work!

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

set the variables and try it

### Ⅴ. Anything else we need to know?

### Ⅵ. Environment:

- K8S Runtime and version:
- OPS CLI version: 0.1.0-2409121919.dev
- Others:

Comienza con la ruta de actualización de la ops CLI y su uso de la Go git library; reproduce el fallo después de establecer HTTP_PROXY y HTTPS_PROXY, y luego rastrea cómo llegan las variables a la operación de git. Se considera terminado cuando `ops -update` funciona a través del proxy configurado, con una comprobación de regresión para las variables de entorno.
