Strip backticks from table name and schema

[romsharon98]

Iceberg quotes namespace/table parts that contain special characters (e.g. the hyphen in silver-stagingdb) when it builds the TableIdentifier string that becomes the Glue symlink facet's name. _parse_glue_table_name never accounted for that quoting, so any Glue database name with a hyphen fails to match a catalogued table, even when the table exists in OpenMetadata under the correct name.
