Fixes #37072 - Made package update choose the correct version

[parthaa]

What are the changes introduced in this pull request?

Package Update now correctly picks the package to update when you chose from a drop down on the host packages tab.

Considerations taken when implementing this change?

When we choose a specific version of package a to update on the host - we try to infer the name and arch of the package to be upgraded. This information is then used to determine how the update command should look. The changes here use the pre-existing Katello::Util::Package.parse_nvrea to figure out the package provided in the template instead of the magical potentially fault regex

What are the testing steps for this pull request?

1. Create a RHEL 9.2 machine with crypto-policies-20221215-1.git9a18988.el9.noarch
2. Sync RHEL 9 appstream + baseos
3. Try to upgrade to crypto-policies-scripts-20221215-1.git9a18988.el9_2.1.noarch via the dropdown on the right side of the upgradable RPM
