Spelling error about 'vacuume' in zh_CN.po

Hi,
I'm doing some testing in PostgreSQL 18, trying to get transaction IDs to
exceed 4.2 billion,
but I encountered the following error:
"警告: 带有OID为4的数据库必须在4293966794个事务中进行清理(vacuume)."
(Because I'm using a Chinese-language environment, the error message is in
Chinese.
I checked the source code and found the corresponding English error:
'database with OID %u must be vacuumed within %u transactions'.)

The error itself is not problematic, but I believe there is a spelling error
in the word "vacuume".
Therefore, I searched the PostgreSQL 18 source code for this word and found
four similar instances,all appearing in the 'src\backend\po\zh_CN.po' file.
I'm unsure how to better fix this—should I change it to `vacuumed` or simply
remove it?
Therefore, I'm submitting this feedback in the hope that this issue can be
fixed in a future version.

Thanks.
