[BUG] rlike cannot run on GPU because invalid or unsupported escape character ']' near index 14

[viadea]

Env:
22.04 snapshot
22.06 snapshot

This is a minimum reproduce:

from pyspark.sql.types import StructType,StructField, StringType, IntegerType
data2 = [("abc[123]",""),
    ("xyz[123","Rose")
  ]

schema = StructType([ \
    StructField("firstname",StringType(),True), \
    StructField("middlename",StringType(),True) \
  ])
 
df = spark.createDataFrame(data=data2,schema=schema)
df.printSchema()
df.show(truncate=False)


simplified_regex = r"^abc\\[([0-9]+)\\]"

df.withColumn('newcol', expr(f"""   firstname rlike "{simplified_regex}"    """)).collect()

The result is:

[Row(firstname='abc[123]', middlename='', newcol=True), Row(firstname='xyz[123', middlename='Rose', newcol=False)]

And rlike will fallback due to "]"
