fix: config typo and small memory fix in extnotes.c

Fix Typos and Enhance Memory Management in tailwind.config.js and extnotes.c

1. Typographical Error:

   • File: tailwind.config.js

   • Issue: a type error

                  mono: ['"Ubunto Mono"', ...mono]
     

   • Solution:

                   mono: ['"Ubuntu Mono"', ...mono]
     

   • It ensures proper recognition of the font, improving the overall aesthetic consistency of the application.

2. Memory Management Improvement:

   • File: extnotes.c
   • Issue: The original code did not safely handle the result of realloc. If realloc failed, it could lead to memory leaks since
     the original pointer would be lost.
   • Solution: Introduced a temporary pointer (temp) to hold the result of realloc. This ensures that if realloc fails, the
     original buffer remains intact and can be freed properly.

   The updated code now checks the allocation:

      if (packetSize > bufSz)
      {
          unsigned char *temp = realloc(buf, packetSize); // Use a temporary pointer
          if (!temp)
          {              // Check if memory allocation failed
              free(buf); // Free the existing buffer to avoid a memory leak
              break;
          }
          buf = temp; // Only assign buf if realloc was successful
          bufSz = packetSize;
      }; 
   

These changes aim to enhance the reliability and performance of the application by correcting minor bugs and improving memory safety.

Hey @Snazzah assign this under the [hacktoberfest2024) :) !!

Other than the styling on the C code, I'm okay with this
