[tt1-blocks] Update deprecated block patterns

[ntsekouras]

This PR updates the deprecated block patterns in tt1-blocks theme.

The diff is kind of rough and not visible.

Some of the deprecations were:

1. Image blocks with align left, right or center needed a div wrapper and the appropriate classes
2. A Group block with the extra div wp-block-group__inner-container
3. Column blocks with a number in width like <!-- wp:column {"width":80}. The current shape has width as a string, so it should be <!-- wp:column {"width":"80%"}

Testing instructions

1. Verify that every pattern's design is not affected and can be inserted with no problems as before
2. Verify that there are no logs produced from deprecated block conversions

In general it should be a good practice to keep block patterns updated and all themes included in core should be updated if needed.

Putting this to draft state as it has been surfaced here: https://github.com/WordPress/wordpress-develop/pull/1483, that a version check for patterns should be added, besides the version check for the theme itself
