Fix regular expression in fact unbound_version.

[sst-yde]

\d matches a single digit, so a version like 1.4.20 will result in the fact unbound_version containing 1.4.2 instead of 1.4.20. The new expression will match a number (one or more digits), followed by any number of dots which are immediately followed by a number. This way we're able to match 1, 1.2, 1.2.3, 1.2.3.4 etc.

Thanks for the PR. Would you be able to add a test for this change? The regex looks good, but a test would make sure this supports the rest of the version strings you've mentioned above.

I've tried to add a test in #173 but it didn't work at first pass. I can come back to look closer later.

Thank you for the PR here. Sorry for such a slow response. I've tried three times now at different time s to get a test that works for this and have failed every time. I've tested this manually and all looks good to me. I'll merge #211 to remove the newline.
