Support for multiple deployments in one comment

### Details

# Hello

I would like to ask if it is possible to replace `context.payload.comment.body` with a specific comment body that is passed through the workflow call.

The reason I’m asking is that I want to support multiple deployments from a single comment. The repository I’m working on contains many different ArgoCD-managed apps (spread across 10+ clusters).

The way we currently use `.deploy` is like this:
```
.deploy app1-enva
```
where `app1` is the application and `enva` is the cluster where we want to deploy it.

I forked the repo about 2 months ago and made it work by building a matrix from the different `.deploy` commands and then running each sequentially. However, the branch-deploy workflow wanted to use the whole comment, e.g.:
```
.deploy app1-enva .deploy app2-envb
```
So I made some changes in the code and replaced `context.payload.comment.body` with a specific `COMMENT_BODY` passed from the matrix (always the one currently deploying). This worked.

Now, I’ve been asked if there’s a way to merge this change back into the original repo so we don’t need to maintain a separate fork.

So my question is: **Is it possible to merge my changes that replace `context.payload.comment.body` with a specific comment body that gets passed in through the workflow call?** Or it would break too many things for other users?

Empieza localizando el workflow branch-deploy y cada uso de context.payload.comment.body; después, compara esas rutas con la entrada de workflow COMMENT_BODY propuesta y con el flujo de despliegue basado en matrices. Comprueba cómo se analiza actualmente un único comentario de despliegue y cómo se transmite a través del workflow. Se considera terminado cuando se pueden procesar varios comandos .deploy de forma independiente sin romper el comportamiento existente para un solo comando.
