Alter knowledge base syntax

[ea-rus]

1. Implemented command to update knowledge base

Example:

ALTER KNOWLEDGE_BASE my_kb
            USING
                reranking_model={'provider': 'openai'},
                embedding_model={'api_key': '123'}

2. Removed unusable yet parser option: 'create kb from select'. It makes parser lightweight a little

mindsdb_sql_parser/parser.py (1)

146-158: ALTER KNOWLEDGE_BASE grammar does not support optional USING clause, so ALTER KNOWLEDGE_BASE my_kb (without USING) will fail to parse, violating SQL contract for optional clauses.

📊 Impact Scores:

• Production Impact: 4/5
• Fix Specificity: 5/5
• Urgency Impact: 3/5
• Total Score: 12/15

🤖 AI Agent Prompt (Copy & Paste Ready):

In mindsdb_sql_parser/parser.py, lines 146-158, the `alter_kb` parser rule only allows `ALTER KNOWLEDGE_BASE ... USING ...` and does not support the clause without `USING`. Update the grammar to also allow `ALTER KNOWLEDGE_BASE identifier` (without `USING`). Add the rule `'ALTER KNOWLEDGE_BASE identifier'` to the `@_` decorator for `alter_kb` so that both forms are accepted.
