chore(release:main): bumps version for release of 1.34.1

[ramsessanchez]

Bumps version for release of 1.34.1.

Changes

• Bumped VersionPrefix from 1.34.0 to 1.34.1 in src/kiota/kiota.csproj and src/Kiota.Builder/Kiota.Builder.csproj.
• Cut the [Unreleased] CHANGELOG section into ## [1.34.1] - 2026-07-09.

Release notes (1.34.1)

• Reduced the aggressiveness of namespace segment and type name shortening by raising the length threshold to 200 characters, so only names longer than 200 characters are truncated (to a 191-character prefix plus an underscore and 8-character hash). The threshold stays well below the 255 file-system per-component limit to leave room for extensions and language-specific suffixes appended by path segmenters and compilers (e.g. Java nested-class .class files and the extra underscores Python adds when converting names to snake_case). #7914
