Index lookups on string primary keys fail on Linux when the database files are created on MacOS

[ray6080]

The bug can be reproduced as following:

1. Create kuzu db on MacOS.

CREATE NODE TABLE DimensionNode(model_key STRING, technical_name STRING, name STRING, aliases STRING[], PRIMARY KEY (model_key));
COPY DimensionNode FROM "<file>" (HEADER=true, DELIM=',');

dimNode.csv

2. Transport the db files on Mac to a Linux machine (I tried it with Ubuntu 22.04.3 LTS).

3. Open the transported db files and run the query, which returns empty.

match (n:DimensionNode) where n.model_key='businessEntity::tpcds_1.tpcds.store' return n;

while, regex matching on scanned tuples can correctly return the matching tuple

kuzu> match (n:DimensionNode) where n.model_key=~'businessEntity::tpcds_1.tpcds.store' return n;
-----------------------------------------------------------------------------------------------------------------------------------------------------
| n                                                                                                                                                 |
-----------------------------------------------------------------------------------------------------------------------------------------------------
| {_ID: 0:11, _LABEL: DimensionNode, model_key: businessEntity::tpcds_1.tpcds.store, technical_name: tpcds_1.tpcds.store, name: Store, aliases: []} |
-----------------------------------------------------------------------------------------------------------------------------------------------------
(1 tuple)
(1 column)

Possibly, this bug can be reproduced between other platforms, but I haven't checked yet.
