chore(cargo): bump mail-builder from 0.4.4 to 0.5.0

[dependabot]

Bumps mail-builder from 0.4.4 to 0.5.0.

Changelog

Sourced from mail-builder's changelog.

mail-builder 0.5.0

• Breaking: The base64_encode, base64_encode_mime, get_encoding_type, rfc2047_encode, quoted_printable_encode, quoted_printable_encode_byte and inline_quoted_printable_encode functions are no longer public. Use the new Base64Encoder and QuotedPrintableEncoder types instead (#50).
• Breaking: EncodingType is no longer part of the public API.
• Breaking: Updated to Rust edition 2024, which requires Rust 1.85 or later.
• Fix: Display names are no longer wrapped in a quoted-string when RFC 2047 encoded, and Q-encoded phrases now escape all characters outside the restricted set.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
