docs: typo fixes Update README.md

[mdqst]

Description

Here’s a typo and a couple of other issues I noticed:

1. "continuous" instead of "contiguous":

   • Typo: "Cairo's memory is read-only... must be continuous."
   • Correction: Replace "continuous" with "contiguous" in this context.
   • Corrected: "Cairo's memory is read-only... must be contiguous."

2. "a yet unused":

   • Issue: Slightly awkward phrasing in "Allocation Pointer (ap) Points to a yet unused memory cell."
   • Suggested correction: Replace with "an unused memory cell."
   • Corrected: "Allocation Pointer (ap) Points to an unused memory cell."

3. "Doesnt":

   • Typo: "Doesnt check anything for the last two."
   • Correction: Add an apostrophe for proper grammar.
   • Corrected: "Doesn't check anything for the last two."

4. "valdation_rules":

   • Typo: "What are these valdation_rules?"
   • Correction: Fix spelling to "validation_rules."
   • Corrected: "What are these validation_rules?"

5. "accesible_scopes":

   • Typo: "A CairoHint contains a code... and accesible_scopes."
   • Correction: Fix spelling to "accessible_scopes."
   • Corrected: "A CairoHint contains a code... and accessible_scopes."

These adjustments should improve clarity and correctness.
