Support pre-releases via new SemanticVersion (#68258)
* Support pre-releases via new SemanticVersion. Fixes #64905 * Don't treat buildmeta as prerelease * Don't inherit from str and int * Add helper method to try and construct a SemanticVersion from a LooseVersion * Don't count major 0 as pre-release, it's different * Guard against invalid or no version in LooseVersion * return a bool * Add integration tests for pre-release * Fix up lingering issues with comparisons * typo fix * Always allow pre-releases in verify * Move pre-release filtering into CollectionRequirement, add messaging when a collection only contains pre-releases * Update changelog * If explicit requirement allow pre releases * Enable pre-releases for tar installs, and collections already installed when they are pre-releases * Drop --pre-release alias, make arg name more clear * Simplify code into a single line * Remove build metadata precedence, add some comments, and is_stable helper * Improve from_loose_version * Increase test coverage * linting fix * Update changelogpull/68417/head
