Code Review

This pull request enhances the documentation for the --initialize-secure command-line flag by providing more specific details about its function. The change is a good improvement for clarity. I've suggested a minor rephrasing to further improve readability and align more closely with the documentation style guide.

[dveeden]

Note that "Bootstraps tidb-server in secure mode" is also confusing as people might expect this to be Security Enhanced Mode (SEM) (see also https://docs.pingcap.com/tidb/stable/system-variables/#tidb_enable_enhanced_security ).
