Value highlighting does not correspond to YAML 1.2 specification

Describe the bug

With a YAML spec of 1.2 chosen in settings (Default) - the highlighting of values does not correspond to the 1.2 specification as some strings are being highlighted as if boolean. It appears that strings that corresponding to boolean from older specification are being highlighted

Expected Behavior

${{\color{lightskyblue}\Huge{\textsf{Stage:\ }}}}$
${{\color{lightskyblue}\Huge{\textsf{ Axis1:\ }}}}$ ${{\color{darkorange}\Huge{\textsf{ X\ }}}}$
${{\color{lightskyblue}\Huge{\textsf{ Axis2:\ }}}}$ ${{\color{darkorange}\Huge{\textsf{ Y\ }}}}$
${{\color{lightskyblue}\Huge{\textsf{ Axis3:\ }}}}$ ${{\color{darkorange}\Huge{\textsf{ Z\ }}}}$

As per https://yaml.org/spec/1.2.2/

Current Behavior

${{\color{lightskyblue}\Huge{\textsf{Stage:\ }}}}$
${{\color{lightskyblue}\Huge{\textsf{ Axis1:\ }}}}$ ${{\color{darkorange}\Huge{\textsf{ X\ }}}}$
${{\color{lightskyblue}\Huge{\textsf{ Axis2:\ }}}}$ ${{\color{lightskyblue}\Huge{\textsf{ Y\ }}}}$
${{\color{lightskyblue}\Huge{\textsf{ Axis3:\ }}}}$ ${{\color{darkorange}\Huge{\textsf{ Z\ }}}}$

No source file, test, or entry point is named in the issue. Start by reproducing the Axis1/Axis2/Axis3 example with the default YAML 1.2 setting and compare the highlighting with the YAML 1.2.2 specification. Done means values that are strings under YAML 1.2 no longer receive boolean highlighting.
