i18n(ja): fix loose wording and stray artifact in binlog_do_db/binlog_ignore_db troubleshooting

[yahonda]

What is changed, added or deleted? (Required)

Two defects in the same troubleshooting section (binlog_do_db/binlog_ignore_db error messages):

1. に似ている場合 (casual "looks similar") is too loose for a technical description of pattern matching against a placeholder-style error message (xxx stands for actual DB names). Changed to に類似している場合, matching the technical register.
2. A stray literal -- was left between two sentences, right before the See [--binlog-do-db=db_name] / See [--binlog-ignore-db=db_name] links. The EN source has no such character here; it appears to be an MT artifact from a dropped "See". Removed it.

Searched the rest of the i18n-ja-release-8.5 corpus for the same stray--- artifact pattern and found one more instance of the identical defect:

3. tiup/tiup-component-dm-template.md (summary: frontmatter): the EN source's "The --full option ..." had "The" collapsed into a literal -- stranded right before the real --full flag name. Removed the stray token.
