Convert OBSE version file anchors to `*versionXofYorGreaterRequired` message sub-anchors

[sibir-ine]

Due to the way requirements work, the OBSE version file anchors don't actually work as intended. If OBSE isn't installed, it will notify the user of the minimum version of OBSE required, but, if they have a lower version installed, the message won't display even though they don't meet the minimum version requirement. Therefore, in order for these anchors to work as intended, they need to be converted to equivalent *versionXofYorGreaterRequired message sub-anchors.

The non-versioned &OBSE file anchor works as intended.

Reopening as *versionXofYorGreaterRequired would be a more appropriate replacement than *requiresX.
