Refactor Value
cell path functions to fix bugs (#11066)
# Description Slightly refactors the cell path functions (`insert_data_at_cell_path`, etc.) for `Value` to fix a few bugs and ensure consistent behavior. Namely, case (in)sensitivity now applies to lazy records just like it does for regular `Records`. Also, the insert behavior of `insert` and `upsert` now match, alongside fixing a few related bugs described below. Otherwise, a few places were changed to use the `Record` API. # Tests Added tests for two bugs: - `{a: {}} | insert a.b.c 0`: before this PR, doesn't create the innermost record `c`. - `{table: [[col]; [{a: 1}], [{a: 1}]]} | insert table.col.b 2`: before this PR, doesn't add the field `b: 2` to each row.
