feat: implement string representation for PartitionFilter

[sonhmai]

Description

Implement string representation for PartitionFilter and add it to optimize command commit info for a TODO.

Following json representations of CommitInfo from delta scala project were found:

"operationParameters":{"predicate":"[\"(id#480 < 50)\"]"}
"operationParameters":{"predicate":"[\"(col1#1939 = 2)\"]"}
"operationParameters":{"predicate":"[\"`col2` LIKE 'data-2-%'\"]"}
"operationParameters":{"predicate":"[\"(id#378L < 2)\"]"}
"operationParameters":{
  "predicate":"[\"(spark_catalog.delta.`/table-uuid`.id IN (0, 180, 308, 225, 756, 1007, 1503))\"]"
}

So I think representing predicate as a list of filters in string representation would be logical, for example:

// single PartitionFilter
"operationParameters":{"predicate":"[\"date = '2022-05-22'\"]"}
// two filters
"operationParameters":{"predicate":"[\"date = '2022-05-22'\", \"country = 'US'\"]"}
