fix: Documentation Corrections and Clarifications

[savvar9991]

1. First change (line 6 in the first file):

There are 6 precompiles implemented in REVM → There are 7 precompiles implemented in REVM

The number of precompiles was corrected from 6 to 7, which is a factual correction as the list indeed contains 7 precompiles.

2. In the kzg.md file, the following changes were made:

a much more bigger scale → a much bigger scale

Justification: Fixed a grammatical error in the comparative form of the adjective. In English, you cannot use both "more" and the "-er" suffix simultaneously to form a comparative degree. It's correct to use either "more big" or "bigger", but not both. In this case, "a much bigger scale" is the correct form.

3. Changes in builder.md (lines 8 and 12):

It allows handle registers → It allows handler registers

Fixed a typo: "handle" was replaced with "handler", which is the correct technical term in this context.

4. Article Addition (line 31):

Functions from one stage are just renamed functions from other stage, it is made so that user is more aware of what underlying function does.
→ Functions from one stage are just renamed functions from other stage, it is made so that the user is more aware of what underlying function does.

Justification: Added the definite article "the" before "user". This is a grammatical improvement as when referring to a specific type of person (in this case, a user of the system), the definite article is required in English.

5. Handler Modification Change (line 160):

They are used to add custom logic to the evm execution but as they are free to modify the Handler in any form they want.
→ They are used to add custom logic to the evm execution but they are free to modify the Handler in any form they want.

Justification: Removed the word "as" which was creating a redundant clause structure. The new version is more concise and clearer, while maintaining the same meaning.
