Bump package version to 6.0.0-prerelease-1

[Copilot]

Updates the Tag Manager package version from 5.0.2 to 6.0.0-prerelease-1 for the next major release.

Changes

• Directory.Build.props: Updated VersionPrefix from 5.0.2 to 6.0.0
• Directory.Build.props: Updated VersionSuffix from empty to prerelease-1

This produces package version Kentico.Xperience.TagManager.6.0.0-prerelease-1.nupkg.

Original prompt

Bump the package version to the next major version for the Tag Manager integration. Update all locations storing the version (such as Directory.Build.props, Directory.Packages.props, .csproj, and where else applicable). Ensure the solution builds and passes formatting with dotnet format. Follow the same process as in Kentico/xperience-by-kentico-azure-ai-search#96. Update changelog or documentation if version numbers are listed. Do not introduce any other change beyond the version bump.
