### What problem does this PR solve?
When running graph resolution with infinity, if single quotation marks
appeared in the entities name that to be delete, an error tokenizing of
sqlglot might occur after calling infinity.
For example:
```
INFINITY delete table ragflow_xxx, filter knowledge_graph_kwd IN ('entity') AND entity_kwd IN ('86 IMAGES FROM PREVIOUS CONTESTS', 'ADAM OPTIMIZATION', 'BACKGROUND'ESTIMATION')
```
may raise error
```
Error tokenizing 'TS', 'ADAM OPTIMIZATION', 'BACKGROUND'ESTIMATION''
```
and make the document parsing failed。
Replace one single quotation mark with double single quotation marks can
let sqlglot tokenize the entity name correctly.
