SNOW-2109891 add RepositoryUrl and replace LicenseUrl with LicenseExpression

[sfc-gh-dszmolka]

Description

SNOW-2109891 - there's a complaint in #1173 that we're missing repository URL in the project, and also using a license URL instead of a license expression.

Apparently, license URL is even deprecated now.

This change attempts to

• replace PackageLicenseUrl with PackageLicenseExpression
• add RepositoryUrl and RepositoryType to the project file (reference)

as it's desired and apparently would improve package visibility.
