Subject: [PATCH] Feat: Generate URI in 'Source' to point directly to a block.

Obsidian already supports URI to a block by block ID through the URI
'obsidian://open?file=file#^block_id'. Please note that the
'file#^block_id' part needs to be URI encoded. Therefore,
the URI in the 'Source' field will be 'obsidian://open?file={file}%23%5E{block_id}'.
