fix(pyo3): correct extract_text_fn call in extract_markdown stub

Browse source 
The extract_markdown stub was calling extract_text instead of
extract_text_fn, causing a compilation error. This fixes the
function name to match the exported function from extract_text.rs.

This completes the extract_text PyO3 entry point implementation,
which was already present in extract_text.rs and lib.rs.

// - Version: 1 (0x00000001)
// - Bit widths: object_number=8, page_offset=16, page_length=16,
// shared_object=8, shared_length=8
// Packed as: 0x81818181 (but we only use 20 bits)
// - Page count: 1 (using 8 bits)
// - Shared group count: 0 (using 8 bits)
// Let's construct this more carefully:
// Byte 0-3: version = 1 (big-endian)
// Byte 4-7: bit widths packed in 20 bits
// Actually, the spec says these are 4-bit values read as bits,
// not as bytes. Let me re-read the spec...
// Re-reading PDF spec Annex F.2:
// The bit widths are stored as a 32-bit integer where:
// - Bits 16-19: object number width
// - Bits 12-15: page offset width
// - Bits 8-11: page length width
// - Bits 4-7: shared object number width
// - Bits 0-3: shared group length width
// For minimal widths: all 1s (so we need at least 1 bit each)
// Let's use: object=4, page_offset=8, page_length=8, shared_obj=4, shared_len=4
// Packed: (4 << 16) | (8 << 12) | (8 << 8) | (4 << 4) | 4
// = 0x04884 (but we need 32-bit alignment)
// Actually, let me look at the spec more carefully.
// The widths are stored as 4-bit values, but they're read bit-by-bit.
// Let me use a simpler approach: construct a valid hint header
// where all widths are 8 bits (for simplicity):
// Byte 0-3: 0x00000001 (version)
// Byte 4-7: 0x08080808 (all widths = 8 bits)
// Byte 8-11: page count = 1
// Byte 12-15: shared groups = 0
// Construct a valid hint header with proper bit-level packing.
// The hint stream uses bit-packed fields that can span byte boundaries.
//
// Format (PDF spec Annex F.2):
// - 32-bit: version (must be 1)
// - 20 bits: bit widths (five 4-bit fields)
// [object_number_bits (4) | page_offset_bits (4) | page_length_bits (4) |
// shared_object_number_bits (4) | shared_group_length_bits (4)]
// - variable bits: page count (width = object_number_bits)
// - variable bits: shared group count (width = object_number_bits)
//
// For this test, we use:
// - All widths = 8 bits (binary: 1000, so each 4-bit field is 0b1000 = 8)
// - Page count = 1
// - Shared group count = 0
//
// The 20-bit bit_widths value is:
// (8 << 16) | (8 << 12) | (8 << 8) | (8 << 4) | 8 = 0x88888
//
// This is packed MSB-first across 3 bytes (20 bits need 3 bytes):
// Byte 0: bits 19-12 = 0x88
// Byte 1: bits 11-4 = 0x88
// Byte 2: bits 3-0 = 0x8 (with 4 zero padding bits = 0x80)
//
// After the version (4 bytes), the bit_widths field starts at bit 32.
// Reading bits 32-51 gives us 0x88888.
