openstack project commands fail with permissions error

Hi,

we've used old versions of openstack-cli in our automation for a while and have upgraded to v9.0.0 but these commands are now failing:
```
openstack project list
openstack project show PROJECT_NAME
openstack project show --children PROJECT_NAME
```
with the following errors:
```
ForbiddenException: 403: Client Error for url: https://XXX/v3/projects, You are not authorized to perform the requested action: identity:list_projects.
ForbiddenException: 403: Client Error for url: https://XXX/v3/projects?name=PROJECT_NAME, You are not authorized to perform the requested action: identity:list_projects.
ForbiddenException: 403: Client Error for url: https://XXX/v3/projects?name=PROJECT_NAME, You are not authorized to perform the requested action: identity:list_projects.
```

The same commands work in v8.3.0 so I think there's been a change/regression between this version and v9.0.0.

I'm guessing it could be something to do with this line or a related change where it now queries an api for the project id but our user doesn't have the identity:list_projects permission:

Note that the following fields are set as env variables:
export OS_REGION_NAME=""
export OS_AUTH_URL=https://
export OS_IDENTITY_API_VERSION=3
export OS_PROJECT_NAME=""
export OS_PROJECT_DOMAIN_NAME=""
export OS_USER_DOMAIN_NAME=""
export OS_USERNAME=""

Thanks
