Fix misc whitespace issues in install docs (#22189)

I ran into issues when copy-pasting the docker-compose.yml contents from
https://docs.gitea.io/en-us/install-with-docker/ - specifically the part
about adding PostgreSQL to the YAML file; I tried manually adding the
diffs by removing the `+` at the beginning of lines, and the resulting
YAML was unparsable.

This forces the indentation to be consistent across all places where
YAML is used.

 Gitea will generate new secrets/tokens for every new installation automatically and write them into the app.ini. If you want to set the secrets/tokens manually, you can use the following docker commands to use of Gitea's built-in [generate utility functions](https://docs.gitea.io/en-us/command-line/#generate). Do not lose/change your SECRET_KEY after the installation, otherwise the encrypted data can not be decrypted anymore.

 Gitea 将为每次新安装自动生成新的 `SECRET_KEY` 并将它们写入 `app.ini`。 如果您想手动设置 `SECRET_KEY`，您可以使用以下 docker 命令来使用 Gitea 内置的[方法](https://docs.gitea.io/en-us/command-line/#generate)生成 `SECRET_KEY`。 安装后请妥善保管您的 `SECRET_KEY`，如若丢失则无法解密已加密的数据。
