[ja] Translated content/ja/docs/tasks/configure-pod-container/migrate-from-psp.md (#48969)

* [ja] Translated content/ja/docs/tasks/configure-pod-container/migrate-from-psp.md

This commit contains several experimental translation for following words:

Validating Admission Controller: (Pod)検証型のアドミッションコントローラー
Mutating Admission Controller: (Pod)改変型のアドミッションコントローラー
Admission controller is mutating: アドミッションコントローラーがPodを改変する
Pod Security Standard: Podセキュリティ基準 (a modification proposal for 「Podセキュリティの標準」)

Note: These words are not officially authorized by any active committers and localization team members.
If these proposal should not be accepted, these words may be simply rewritten in alphabet or カタカナ語 (IMO).

Further discussion needed.

* Update content/ja/docs/tasks/configure-pod-container/migrate-from-psp.md

remove reviewer fields

* Fixed typo on content/ja/docs/tasks/configure-pod-container/migrate-from-psp.md

* Updated content/ja/docs/tasks/configure-pod-container/migrate-from-psp.md

To meet the newline rule on translation style guide (https://kubernetes.io/ja/docs/contribute/localization/#style-guide).
For exception, markdown list or numbered list begining with `-` or `N.` are ignored to apply the newline rule.

* [ja] Removed experimental translation for admission controler terms in migrate-from-psp.md, fixed format.

Updated content/ja/docs/tasks/configure-pod-container/migrate-from-psp.md:

* to replace `(改変型|検証型)アドミッションコントローラー` with `(Validating|Mutating) Admission Controller`.
* to replace the word `改変` with `変更` to naturally follow the changes above.
* to fix the markdown format to suite the translation style guide.

The removed trial translations of Admission Controller-related terms may be discussed again.
So these proposals are not required for the purpose of the PR, they are removed.

* [ja] fixed translation variation in notion in migrate-from-psp.md: Pod Security level

The variaty of translation for `Pod Security level` is eliminated and it is unified to
`Podセキュリティの水準`.

* Apply suggestions from code review
