Allow for unexpcted version names in checks & remediations
Summary:
Upgrading from a wiped bletchley fails, due to image version name validation in flashy checks and remediations
```
2024-03-13 02:41:18.275510 - Unsafe to reboot error: "Unable to parse version info: No match for regex 'bletchley-v(?P<year>[0-9]+).(?P<week>[0-9]+)' for input 'bletchley-9e5605ae7d-dirty'".
```
We should allow for Flashy to upgrade from versions without a `vYYYY.WW.N` version tag, such as the OSS image build or locally built versions, and only proceed to the year check if it's an actual date tagged version
Test Plan:
Test upgrade from same device:
```
$ oobgrader --host macbmc5r0034p0049-oob.02.pci1.facebook.com --fbpkg-name openbmc.image.bletchley:weeklybuild --flashy-tag e44d3bf --wait
Host Workflow ID Progress Status Result

```
Test upgrade on wedge100 to ensure normal behaviour
```
$ oobgrader --host fboss8382003.snc1 --primary-only --wait --force --flashy-tag e44d3bf --allow-downgrade
