fix(pageserver): handle version number in draw timeline (#8102)

Browse Source 
We now have a `vX` number in the file name, i.e.,
`000000067F0000000400000B150100000000-000000067F0000000400000D350100000000__00000000014B7AC8-v1-00000001`

The related pull request for new-style path was merged a month ago
