docs: fix typos and grammar in glossary.md

[Alice699]

What was fixed

• "they are" → "It is" (subject-verb agreement)
• "AccountComponent's" → "AccountComponents" (plural)
• "transfering" → "transferring" (spelling)
• "composed or four Felt's" → "composed of four Felts" (grammar + spelling)

Small but important improvements for better readability. First-time contributor PR.

Hey @BrianSeong99 , I opened PR #176 a while ago is there anything I need to fix or clarify? Just want to make sure it's ready for review, Thanks

[BrianSeong99]

Thanks for catching these typos! Reopened — these look good. Will merge shortly.
