There is currently no way to re-map where shared modules can be found on disk.

**Is your feature request related to a problem? Please describe.**
We have a shared folder with modules, used by different projects that all have relative links to those modules ../../shared
This works fine locally but not in CI.

**Describe the solution you'd like**
I'd love to be able to specify an alias for a shared folder simlar to how the bicepconfig already allows you to alias templatespecs.

local:
```
{
"moduleAliases": {
"file": {
"SharedModules": {
"path":"../../shared'
}
}
}
}
```

CI: (after replace in json)
```
{
"moduleAliases": {
"file": {
"SharedModules": {
"path":"dist/shared"
}
}
}
}
```

In code:

```
module containerAppModule 'shared/container-app.bicep' = {
name: 'containerAppModule'
``

Start with bicepconfig's existing templatespec alias support and the moduleAliases examples in the issue. Trace how file module paths are resolved in local and CI layouts, then define done as resolving the same shared/container-app.bicep reference through a configurable SharedModules alias in both configurations.
