OSL-2.0: Fix “Licensev.” → “License v.”

[wking]

The typo came in with the license in 0162ea9 (Automated, 2016-03-30, #180).

Also add an optional “The ” to match the archived original:

$ curl -s https://web.archive.org/web/20041020171434/http://www.rosenlaw.com/osl2.0.html | grep 'Open Software License' | head -n2
<!-- End Wayback Rewrite JS Include --><h1>The Open Software License<br/> v. 2.0</h1>
<p>This Open Software License (the "License") …

Rebased around #593 with 7f59223 → 46070f1.

the title - in terms of no "the" and using "v" instead of "version" follows the guidelines we've used since day 1 for all license titles: https://spdx.org/spdx-license-list/license-list-overview#fields
while I understand now (as per discussion on today's legal call with @goneall ) that this could cause issues for tools/matching - I'm not sure it has so far?
we should fix the missing space as that is purely a typo introduced recently, but I don't think we need to add "the" - if we do that here, then we have a bunch more we may need to do that for. To what value does this add? (again a question for the tool vendors)

In master, running the matching tests which landed with #593:

$ git describe
v3.0-38-gaaf585c
$ sed -i 's/Licensev/License v/g' test/simpleTestForGenerator/OSL-2.0.txt
$ make TEST_DATA=test/simpleTestForGenerator validate-canonical-match
…
The following warning(s) were identified:
        Test for license OSL-2.0 failed: Test for license ID OSL-2.0 failed due to difference found Normal text of license does not match starting at line #1 column #5 "software" when comparing to template text "
This Open Software License (the "License") applies to any original work of authorship (the "Origina...".  Last optional text was not found due to the optional difference: 
        Normal text of license does not match starting at line #1 column #22 "v" when comparing to template text " Open Software Licensev. 2.0"
Completed processing licenses
…

so unless we add the space to the title, our own test suite will fail to match license text that correctly includes the space. I think that's enough for “has caused an issue with tools/matching”.

… I don't think we need to add "the" - if we do that here, then we have a bunch more we may need to do that for. To what value does this add? (again a question for the tool vendors)

This has the same spdx/tools matching issues as the space above. If we want to match both the upstream text I linked in the commit message (which includes “The”) and our traditional SPDX text (which does not) we need to use either an <optional> or <alt> around the optional “The”. I think we do want to match both the upstream text and our own previous text.

Since the changes will help the matching, I'll go ahead and merge the changes.
