I think you have a dependency issue my dear Fabien :)

? texei-sfdx-plugin isn't signed by Salesforce. Only install the plugin if you trust its creator. Do you want to continue the
installation? yes
Because you approved this plugin, you can avoid future installation confirmations by adding the plugin to the unsignedPluginAllowList.json file. For details, see https://developer.salesforce.com/docs/atlas.en-us.sfdx_setup.meta/sfdx_setup/sfdx_setup_allowlist.htm.
Finished digital signature check.
