…in/ instead of ~/.cargo/bin.

As of v0.5.0 of uv, uv is installed to ~/.local/bin instead of ~/.cargo/bin. This would cause issues in reportifyr for most functions. In this PR we introduce a get_uv_path() function to utils.R to determine if ~/.local/bin/uv or ~/.cargo/bin/uv exists and returns the path found with a preference to ~/.local/bin/uv if they both exist.

• Use XDG (i.e. ~/.local/bin) instead of the Cargo home directory in the installer (#8420)

Previously, uv's installer used $CARGO_HOME or ~/.cargo/bin for its target install directory. It's been a longstanding complaint that uv uses this directory, as there's no relationship to Cargo. Now, uv will be installed into $XDG_BIN_HOME, $XDG_DATA_HOME/../bin, or ~/.local/bin (in that order). Note that $UV_INSTALL_DIR can always be used to override the target directory. Upgrading with uv self update will not move uv to the new install directory.
