tgswitch: init at 0.5.378

Add tgswitch which allows to easily manage different terragrunt
versions for different projects.

Tested it locally on a NixOS machine:

```
❯ tgswitch --help

Usage: tgswitch [-hv] [-b value] [parameters ...]
 -b, --bin=value  Custom binary path. For example:
                  /Users/username/bin/terragrunt
 -h, --help       displays help message
 -v, --version    displays the version of tgswitch
Supply the terragrunt version as an argument, or choose from a menu
```
