Revert version of schema to 0.6.10 since we have not yet released it

[yarikoptic]

Currently we have

❯ git describe schema-0.6.9
schema-0.6.9
❯ git describe --match 0.* schema-0.6.9
0.11.0
❯ git describe
schema-0.6.9-22-g84bef7e
❯ git describe --match 0.*
0.11.0-22-g84bef7e

so we have 0.6.9 schema released in prior (current) 0.11.0 release of this package. So the next release needs to just boost schema version once.

We will also take this PR as an opportunity to release (attn @kabilar , you wanted that didn't you?)

Thank you, @yarikoptic.

@satra @waxlamp , anything else we should fold into this release or let's proceed? IIRC should be only simple straightforward schema changes.
