Fix typos and improve grammar in README

[hasanerdemak]

Corrected several typographical errors and improved grammar throughout the README for better clarity and professionalism. Changes include fixing word forms, possessives, and minor phrasing issues.

• "memory.." -> "memory."
  Removed the extra period for correct punctuation.

• "Transformers's chat template" -> "Transformers' chat template"
  Fixed the possessive form for the plural proper noun Transformers.

• "webserver" -> "web server"
  Converted the compound word to the standard two-word form for clarity and consistency.

• "python 3.12" -> "Python 3.12"
  Capitalized Python because programming-language names are proper nouns.

• "To run the reference implementation. Install dependencies:" -> "To run the reference implementation, install the dependencies:"
  Merged two sentence fragments, added the article the, and replaced the period with a comma for smoother flow.

• "Or downloaded the pre-converted weight:" -> "Or download the pre-converted weights:"
  Corrected verb tense (present imperative instead of past) and made weights plural.

• "a basic example on how to use" -> "a basic example of how to use"
  Replaced the incorrect preposition on with of.

• "as a inference solution" -> "as an inference solution"
  Switched "a" to "an" because inference starts with a vowel sound.

• "every two value" -> "every two values"
  Added the missing plural s for noun–verb agreement.

• "recommend use BF16" -> "recommend using BF16"
  Changed use to the gerund using to fit the verb construction "recommend + gerund".
