update(plugin-json): point to the correct Semgrep plugin directory

The Semgrep plugin currently does not work correctly when used through
Claude because it is located within a subdirectory of the Semgrep
Marketplace repository. This issue was reported in:
https://github.com/anthropics/claude-plugins-official/issues/450

Previously, this could not be fixed due to a limitation in Claude Code's
handling of plugins located in subdirectories. Support for this was added
with the git-subdir feature, released in v2.1.69:
https://github.com/anthropics/claude-code/issues/30593

A fix for the Semgrep plugin was proposed once this version became the
latest release. Now that v2.1.69+ is available as latest, this PR
implements that fix.
