A solution in QGIS.

Step 1: Buffer your polygons by 10 m and dissolve while buffering.

Step 2: Run multi to single-part on your buffers.

Step 3: Use $id in the field calculator to add a unique ID to your buffers.

Step 4: Join attributes by location in order to add your buffer-IDs to your original polygons.

Step 5: Dissolve based on the added IDs.
