Inconsistent use of quotes in trademarks document

"Marks" and "Mark" appear throughout https://github.com/github/MVG/blob/main/org-docs/TRADEMARKS.md in a few different forms both with double, single and no quotes. It appears that the intent is to substitute the actual name of a trademark for "Mark" in some places. This could be made clearer.

打开 org-docs/TRADEMARKS.md，检查“Mark”和“Marks”的每次使用，包括使用双引号、单引号以及不使用引号的版本。确定一种一致的约定，使预期的替换清晰明确，然后确认该文档始终使用这一约定。
