Module metadata displays versions as strings, not integers

[nazunalika]

Describe The Bug

Module metadata produced erroneously produces a version as a string, not an integer which will cause issues with content management systems.

Reproduction Steps

1. Sync content in pulp

Expected Behavior

Version should not be quoted as a string.

Version and Build Information

Current.

Additional context

https://bugs.rockylinux.org/view.php?id=2575

[nazunalika]

Likely erroneous line:

peridot/modulemd/modulemd.go

Line 130 in 6e752a3

Version string `yaml:"version,omitempty"`

YAML spec for modulemd states it as a 64-bit unsigned integer.

This would involve auto fixing existing metadata during first sync (post type change), but not super difficult I hope
