Fix Typos, Poor Wording and English Errors

[GraphR00t]

Typos and poor wording in any text or piece of text in the codebase should be fixed in this issue.
Pull requests will not be accepted.

For example if you find an error in some messages, you can just write a comment of the following format:

• internal/parse/parse_error.go:49 change it do with it does
• internal/parse/parse_error.go:50 change graet with great

From time to time I will make a commit with several proposed changes. Thank you for your contribution !
