Update README.md

Waiting for the upload of screenshots
I have a good idea about the screenshots. I will do it later.

If you have screenshots already, you can upload them here and I'll upload them to dl.gitea.com

I have sent them to @lunny yesterday.

I have a new idea about how to update screenshots automatically. I should do some prepares, so in this PR I will not touch it.

中文 README 请保持使用全角顿号、逗号、句号。目前新增的段落都存在混用的情况。

The Chinese-language README should using full-width characters. Currently we had a mix of full-width and half-width characters usage in the newly introduced contents.

@BLumia
原来的中文README中就存在半角全角符号混用。所以我在修改的时候就很confuse。如果有这个规定，我会重新检查所有符号。

The original Chinese README already had a mix of full-width and half-width characters, which made me quite confused while editing. If there is such a rule, I will go back and thoroughly check all the symbols.

e.g. https://github.com/go-gitea/gitea/blob/main/README_ZH.md#%E6%8F%90%E7%A4%BA

我知道，所以觉得既然比较大篇幅的修订就可以顺带改掉来着。
I know, that's why IMO we can also address this issue since you already rewriting/reworking the content itself.

If there is such a rule

现在应当没有这个规定，但出于文本规范性角度而言，建议进行修正。
I believe we don't have such guideline for now, but from the perspective of textual standardization, I suggest we also address this issue here.

（如果你完全没有计划在这个 PR 做这件事的话，可以说一下，我就不因此 request change 了）
(if you don't intended to do this, let me know and I'll no longer request change for this issue)

No, this request makes sence, will be done in this PR.
