#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.

Compiles, tests pass, help texts look good in both languages. Left two comments below I'd want addressed before merging.

[Ali-Shariati-Najafabadi]

Not sure this actually installs anything on mac/linux. doInstall() extracts to a tmp dir, runs the first executable it finds, then deletes the tmp dir right after. For the mac DMG case that just opens the app once and wipes it. Docker handles this by overriding getInstalledVersion() with a check against /Applications/Docker.app — Obsidian doesn't, so it'll probably never register as installed on mac. Given ide-urls has no obsidian entries yet, this is untested — worth a real check once that's in place.

You're right, on mac/linux doInstall() just runs the first executable it finds and then deletes the tmp dir, so nothing gets installed. Also ide-urls has obsidian now and linux_x64 is a .deb, not a .tar.gz.
I've only tested on Windows. Can we keep this PR Windows-only and open a follow-up for mac/linux?
I mean open a separate issue for that?
