CompatHelper: bump compat for PrettyTables to 2, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the PrettyTables package from 0.12, 1 to 0.12, 1, 2.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.

Hi,
Using your package a lot, can you update the compatibility with PrettyTable ? The commented row are still problematic with the input in PrettyTables function with doesn't have them anymore.

pretty_table(io, ds;
alignment = alignment,
alignment_anchor_fallback = :r,
alignment_anchor_regex = alignment_anchor_regex,
body_hlines = extrahlines,
compact_printing = compact_printing,
crop = crop,
crop_num_lines_at_beginning = 2,
ellipsis_line_skip = 3,
formatters = pt_formatter,
header = (names_str, names_format, types_str),
header_alignment = :l,
hlines = [:header],
highlighters = (_PRETTY_TABLES_HIGHLIGHTER,),
maximum_columns_width = maximum_columns_width,
newline_at_end = false,
# show_subheader = eltypes,
# row_label_alignment = :r,
# row_label_crayon = Crayon(),
# row_label_column_title = string(rowlabel),
# row_labels = row_names,
row_number_alignment = :r,
row_number_column_title = string(rowlabel),
show_row_number = show_row_number,
title = title,
vcrop_mode = vcm,
vlines = vlines,
kwargs...)

the problem is that if we allow older PrettyTable releases, some of its functionalities wouldn't work, i.e. newer versions of IMD will not work properly.

I guess your issue should be resolve in PrettyTable.
