fix(config): use SCW_CLI_CONFIG_PATH with set config

Description

The SCW_CLI_CONFIG_PATH environment variable is used to specify a custom configuration path but it was not used consistently inside the config sub commands

You can now setup a config with

SCW_CLI_CONFIG_PATH="./my_config.yml" scw config set \
    access-key=<UUID> \
    secret-key=<UUID> \
    default-project-id=<UUID> \
    default-region=fr-par \
    default-organization-id=<UUID>

And use the environment variable to use the configuration file in further commands

SCW_CLI_CONFIG_PATH="./my_config.yml" scw config info
ConfigPath                       ./my_config.yml
ProfileName                      default
Profile.access-key               ***
Profile.default-organization-id  ***
Profile.default-project-id       ***
Profile.default-region           fr-par
Profile.secret-key               ***

Should address this issue
