Validator Versioning

[AlejandroEsquivel]

Changed:

• Updated Installation process to install from Guardrails Hub PyPi
• Removed forced installations to guardrails/hub folder in site packages and sequential installations of dependencies
• Support for validator versioning (see examples bellow)
• All installation of validator packages and dependencies fully managed by pip
• Added stderr logging on pip subprocess failures to surface any errors like no matching distributions (when no versions available based on provided version ranges)
• Display which version gets installed on installation messages (stdout)
• No more redundant re-installations since installs now just using pip

Examples:

$ guardrails hub install hub://guardrails/detect_pii~=1.4
$ guardrails hub install hub://guardrails/detect_pii>=1.4,==1.*
$ guardrails hub hub://guardrails/detect_pii==1.4.0

from guardrails import install

install("hub://guardrails/detect_pii~=1.4")
install("hub://guardrails/detect_pii>=1.4,==1.*")
install("hub://guardrails/detect_pii==1.4.1")
install("hub://guardrails/detect_pii>1.0.0,<2")

Example Output:

Installing hub://guardrails/detect_pii...
✅ Successfully installed guardrails/detect_pii version 1.4.1!
