#2103: Integrate Obsidian

[Paras14]

This PR fixes #2103

Implemented changes:

• Added Obsidian commandlet extending GlobalToolCommandlet, based on the URL Updater from Create ObsidianUrlUpdater #2186 (#2186: create obsidian url updater #2203)
• Windows: the downloaded installer .exe is executed and not extracted
• macOS: the .dmg is extracted so the *.app can be taken out of it
• Linux: the .tar.gz is extracted
• Registered the commandlet in CommandletManagerImpl
• Added help texts in English and German
• Added Obsidian to the table of tools in documentation/LICENSE.adoc
• Added ObsidianTest covering registration, tags and the per-OS isExtract() branches

Testing instructions

1. Run mvn clean test. ObsidianTest and HelpCommandletTest should pass.
2. Run ide help obsidian and ide --locale=de help obsidian. The English and German help texts should be shown.
3. Run ide install obsidian on your platform and check that Obsidian is installed.

Note on step 3: ide-urls currently contains no metadata for obsidian, so version resolution
fails and the installation cannot be tested yet. The metadata is only created once the URL
Updater from #2186 has run.
