Remove language-server configuration in integration tests
This change removes language server configuration from the default languages.toml config for integration tests. No integration-tests currently depend on the availability of a language server but if any future test needs to, it may provide a language server configuration by passing an override into the `test_syntax_conf` helper. Language-servers in integration tests cause false-positive failures when running integration tests in GitHub Actions CI. The Windows runner appears to have `clangd` installed and all OS runners have the `R` binary installed but not the `R` language server package. If a test file created by `tempfile::NamedTempFile` happens to have a file extension of `r`, the test will most likely fail because the R language server will fail to start and will become a broken pipe, meaning that it will fail to shutdown within the timeout, causing a false-positive failure. This happens surprisingly often in practice. Language servers (especially rust-analyzer) also emit unnecessary log output when initializing, which this change silences.pull/4397/head
