Added an extra check for the case where you upgrade from a pre-release to a stable version.

Technical notes summary

• Added the isUpgradeFromPreToStable function to shell/utils/version.js to detect upgrades from pre-release to stable versions.
• Unit tests

Areas or cases that should be tested

As described in the issue's description install an older pre-release version of a chart(e.g. Kubewarden), then go to the chart's detail page and select versions above and below it and check the action button to make sure it display the correct wording, then by clicking on the action button go to the install wizard page to check the correct wording there too.

Areas which could experience regressions

• Install an older stable version of a chart and do rest checks the same as above.
• Some charts have versions like 108.0.0+up0.25.0-rc.4(e.g. Rancher Turtles - the Cluster API Extension) those should be tested too.
