Bug

Which Delta project/connector is this regarding?

Describe the problem

If a delta table shared by delta share contains any column that has a " character in its comment, com.fasterxml.jackson.core.JsonParseException raises an exception.

Steps to reproduce

  1. Create a delta table (we are using Databricks)
  2. Add a comment in any column: image
  3. After creating the share and recipient, with proper privileges, run a query against the object: 
    
table_path = f"{cred_path}#test_share.default.titanic_table"
df = spark.read.format("deltaSharing").load(table_path)

df.display()

4. The code raises an exception:

<!-- What happened?  This could be a description, log output, etc. -->

#### Expected results

We expect the query to run, it does when I change the comment removing the `"`:

Running the same code:

#### Further details
I tested adding quotation marks to the table comment (description) and there are no problems, only in the column comments.
