Fix Suggestions in CLI Output

Added

• cli: rendering of diffs for suggestions in output. (#662)

  We now include a diff below the rule error.

  warning[require-concurrent-index-creation]: During normal index creation, table updates are blocked, but reads are still allowed.
     ╭▸ example.sql:10:1
     │
  10 │ CREATE INDEX "field_name_idx" ON "table_name" ("field_name");
     │ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
     │
     ├ help: Use `concurrently` to avoid blocking writes.
     ╭╴
  10 │ CREATE INDEX concurrently "field_name_idx" ON "table_name" ("field_name");
     ╰╴             ++++++++++++
  

Fixed

• parser: parsing some set related commands. (#657)

  The following now parse:

  set schema 'foo';
  set foo.bar from current;
  set bar from current;

Changed

• internal: bump rust to 1.90.0 (#659)
• syntax: fill out more of the ast (#658)
